Among the hypotheses
conceived by
scholars about the possible manufacturing processes employed by 16th
and 17th centuries string makers to produce all-gut bass strings, that
of loading the gut by means of appropriate treatments deserves serious
consideration, on the ground of direct and indirect confirmations at
our disposal. This confirmations homogeneously coming from different
fields, each on its own account, allow us to sketch an altogether
sufficiently clear picture of how, in the 2nd half of the 16th century
and for over a hundred years, the problem of acoustical performance of
all-gut bass strings could have been solved by ancients.
As it is well known,
when, in an
attempt to perform renaissance and baroque repertoires observing
philological criteria, modern gut strings are employed for the lower
registers of plucked and bowed instruments, they unequivocally give a
very poor acoustical performance. As a consequence, when performing
musical material from these historic periods, we are always faced with
an all but negligible paradox, stemming from the fact of having
unavoidably to employ overspun strings for music conceived before their
historic
appearance. With some
families of instruments, such as viola da gamba the problem of
acoustical performance for modern gut strings begins normally to appear
already beyond the 4th string, rapidly to became more serious for the
lower ones. With lutes, the consequences are even more striking, and
begin to appear, roughly, after the 5th course and particular in the
lower ones, especially if all lying over one neck of limited length,
such as, for instance 11 course baroque lutes. A very good example of
which appears in the famous portrait of lutenist Charles Mouton (1).
The hope of
unravelling the
mystery behind the manufacturing techniques once used to produce
all-gut bass strings (which after the introduction of overspun strings,
were to fall in progressive and irreversible neglect) spurred an
intensive research on the part of scholars who, once ascertained that
modern thicker strings are rather stiff, thought that the heart of the
problem was to be sought in the twisting process commonly employed
today, which does not allow a sufficient degree of elasticity; an
important parameter to make a string sonorous (2).
The amount of twist
thus began to
be considerably increased, seen that it allowed some increase in the
elasticity of the structure (3). Unfortunately, in the region of the
lowest frequencies such procedure proved insufficient. So other more
complex twisting methods were adopted (4)(5), some of which reproduce
exactly the structure of a rope. By proceeding in this direction a
noticeable decrease in the string's stiffness was finally arrived at
the cost of loosing its smoothness, which is at odds with many written
and iconographical sources of the 16th and 17th centuries. This caused
some dispute about the historical reliability of such a manufacturing
process (6).
This, in short, can be
considered
the state of experimentation which is certainly made more difficult by
the fact that no old string from the 16th or 17th centuries seems to
survive today. Likewise, very little of technological significance
comes to us from treaties of the past and from recently discovered
string makers statutes (7)(8). The string makers' secrets were
carefully guarded, an easily understandable attitude in times when
there were no certain commercial guarantees, while fraud lied
constantly in ambush. In the string makers corporation statute in
Rome
(1642) and
Naples (1653 and 1685) for
example, the only technologically relevant information seems to be the
prohibition to
shear (longitudinally?) gut and what the size
the frames should be. In fact, most chapters deal with prevention and
repression of frauds.
1. Bridge holes
The hypothesis that
the loading of
gut could have been the common and relevant characteristic of bass
strings employed between 16th and 18th centuries found its way in the
light of some data recording, which afterwards became systematic, of
bridge holes
sizes from historic
lutes built before, or very close to 1664, year to which the earliest
surviving historic report of overspun strings date back to (9). It
should be underlined, however, how scant and scattered the spreading of
the new type of strings must have been, probably on the ground of the
habit musical taste, and the fact that traditional bass strings in the
face of the novelty, kept being competitive. T. Mace (10) over ten
years after J. Playford's announcement, make no mention of them. J.
Talbot (11) by then prefers to use conventional bass strings, and so
does L. Mozart who well into the 18th century, implicitly excludes, in
his 1756 violin tutor, the use of overspun strings.
For the lute the bond
to old habit
remains very strong. Gut bass strings of
"...
a deep dark red colour ..." (12) can be seen
in a portrait by the berliner painter A. Pesne (1678-1758) painted
around 1740-2 and now in the Schloss Charlottenburg, Berlin, portraying
the graceful Eleonore von Kayserling playing a 13 courses German
theorbed lute, probably tuned in D minor. Thus, on the ground of such
observations, some of the original instruments examined are from a few
decades after the watershed implicitly established by Playford's
announcement.
In practical terms the
lowest
courses' hole diameters in original instruments bridges were found to
be so small as to allow no all-gut string passing through them a
sufficient working tension and therefore a sufficient sonority, a
sonority moreover only granted to strings possessing a high degree of
elasticity such as rope structured ones for instance, since plain gut
strings, even at working tension considered correct, proves to be
totally unusable. In table 1 some significant examples of very
accurately measured instruments are recorded. These lutes were
presumably tuned in renaissance tuning, possible doubts or further
remarks are recorded aside. The low strings holes were measured by
means of rods of increasing known diameters, thus the maximum passing
diameter was found. When examining these data it must be borne in mind
that we are dealing with bridge holes diameters and not strings
diameters, which were bored by the lute maker with some amount of
empirical oversize. In spite of this handicap, the results are
absolutely surprising.
Before examining the
data in the
tabs, it will be useful to briefly remind some considerations, quite
often treated anyway, on the physics of strings (2)(3). Breaking point
define the tension at which a string of 1mm in section breaks for
modern gut. This is estimated at about (13). At equal vibrating length,
gut strings of different diameters will break, theoretically, at the
same frequency (breaking frequency) (14). Through the general equation
for strings, it can be inferred that the product of this critical
frequency by the string vibrating length (in meters) is a constant K
(breaking index). Such relation when expressed in other terms ( ) allow
to quickly calculate the theoretical upper limit at which the cantino
of each historical instruments examined will break.
The common procedure
for tuning a
lute (or a viola) for solo playing in 16th century was, as well known,
to tune up the treble, empirically, to the highest possible pitch,
stopping short of breaking (i.e. before reaching its breaking point).
In other words one aimed for the highest working frequency a given
string vibrating length will allow. Keeping slightly below breaking
frequency, ancient musicians obviously aimed for an acceptable
compromise between the top string's playing life and the safeguard of
the best acoustic performance of the all-gut lower registers. For
instruments with a defined nominal pitch-tuning it is to be expected
that the procedure could have taken a perfectly specular route,
exploiting, in practice, the maximum string vibrating length which the
breaking point, or rather the breaking frequency allowed. Thus at
playing pitch the treble worked in any case close to the breaking. Such
a hypothesis finds confirmation in the estimates made on the lute
depicted in M. Pretorious "Syntagma Musicum", Wolfenbüttel
1615-20, where the product of frequency by vibrating length is (15).
Basing themselves on
these
concepts several scholars today suggest that working at 2-3 semitones
below breaking frequency may be considered a reasonable choice (2)(16).
For our table it was decided to work at two semitones below the
breaking frequency of each historic instrument. Bearing in mind that
the internal between courses are constant, it was the possible to
assign each course a definite frequency. It is worthwhile to remind
that under these working condition a chantarelle, no matter what its
breaking is, exploits some 80% of its total strength "reserve".
In absolutely
empirical terms, it
may be assumed that at more then 4kg tension, at the strings lengths
examined, a string becomes too stiff to sound, played with finger pads,
with "grace" and "full pearls" (17). At tensions lower
than 2.5 Kg the "focus" of the note produced (basic frequency with its
baggage of higher harmonics) becomes decidedly imprecise, especially
with fairly thick gut strings, where the inner damping coefficient is
rather pronounced. The treatises of the past confirm for their part
that the strings should feel neither too stiff nor to slack to the
touch (15)(18); for sheer convenience, the value of 3 Kg was chosen, a
working tension at which there is a tendency to play today.
As far as specific
weight is
concerned, two different ones where considered: that of usual plain gut
(about ) which although lacking any practical application for the
manufacturing of bass strings possesses the highest density value for a
natural product, beyond which it is only possible to go by means of
appropriate treatments. The other is the mean apparent specific weight
of a rope-construction string, which represent, in fact, the only model
devised today as a possible technological solution employed in the
past, and whose density is around .. By processing these parameters
(density, string length, frequency) (19), it was possible to tabulate
the following:
Column A: the
diameter (in
mm) which a traditional plain gut string (a) or a rope-construction one
(b), at 3.0 Kg tension should possess in order to produce the
corresponding working frequency, assuming a treble, working at two
semitones below breaking point.
Column B: the
specific
weight which strings passing through each bridge hole, at 3.0 Kg
tension, should possess for a working frequency assigned to bass,
according to the above mentioned criteria. As can be easily noticed,
the densities so obtained are rather higher than those of the two types
of strings considered.
Column C: the
tension in Kg
each type of strings (a or b) would have at diameters equal to those
recorded from original bridges. This last column looks rather
interesting, since the only significant variable is represented by the
breaking point of gut, which in turn determines the working frequency
to assign to each bass course.
For sheer curiosity we
have
considered also the mean value of the breaking point of specimens of
current commercial strings (sheep and beef) which is 34 (they range
between 31 and 38 ) but the resulting working tensions were for the
most part below any acceptable value. Finally, the hypothesis was
considered that treble strings of the 16th and 17th centuries may have
been remarkably stronger than those available today, in order to allow,
at equal vibrating length, a higher pitch and therefore move the
working tensions up to a range of values which could be judged
acceptable. Through the string equation, it was estimated that it would
be necessary to reach a breaking point of at least 40 to 48 , which
seems frankly excessive.
Being the product
between the
vibrating length and the breaking frequency (or the working frequency)
for the cantino a constant, we can assume that the same product
for each course is a constant as well, so the knowledge of the
vibrating length becomes inessential to determine some important
parameters as the specific weight and the working tension. Thus is
sufficient to know the bridge hole diameter to obtain what is
necessary, and is no more a possible source of doubts the possibility
that in the past some bridges of the historic instruments observed
could have been moved in a new position, different from the original
one.
For baroque lutes with
a d-minor
tuning, the influence of the breaking point of gut on the data
processing looses completely significance. The top string of these
instruments is always nominally defined as f', whose actual
frequency depends solely from the pitch standard in use, for example kammerton
for German lutes in the 1st half of the 18th century (20). In table 2
examples are recorded of this type of lutes; the method used is
substantially different from the preceding table, owing to the fact of
being able to define more accurately the nominal pitch of each course.
In order to be able to
assign them
an accurate working frequency, the whole range of frequencies was taken
into account, which scholars have considered as valid pitch standards
in use in Europe in the 17th an 18th centuries, with particular
attention to France and Germany; a range of frequencies, which is in
any case included, between a minimum of zero semitones (0s) and a
maximum of two semitones (2s) below our present standard of 440 Hz
(21)(22).
A simple check using
the method of
table 1, suggests anyway to exclude some values in the higher side (0s,
and 1s for vibrating length greater than 0.71 m). With the vibrating
length of baroque lutes we would have a breaking frequency for the top
string too close to these values. Thus parameters computed for a
frequency standard referred as 0s (and 1s for vibrating length greater
than 0.71 m) assume a purely speculative meaning.
The great importance
of this table
must not be overlooked, owing to its being in no way dependent on the
breaking point of gut, a fact which drastically reduces the degree of
uncertainty of the processed data.
Column C for
instance, is
only conditioned by the standard pitch assumed as basis. The specific
weight used for these calculations is that of a rope-construction
string. The information given by Baron (top string equal kammerton
f') suggests some considerations on the breaking point of treble
strings in the 18th century. A large number of surviving instruments
from that period have a vibrating length of between 0.70 to 0.72 m
Assuming a top string working at two semitones below breaking point (by
which it should last 3-4 weeks before breaking, in accordance with both
modern and Baron's indications) at the frequency range hypothesised by
scholars for German kammerton (a' = 440 ÷ 390 Hz) it is
simple to calculate a breaking point "window" of 32÷36 (23),
that is remarkably close to those measured in modern commercial gut
strings.
By following the same
procedure it
is possible to try and work an estimate of the breaking point of the
treble strings of the 16th and 17th centuries. Several lutes built in
Venice in the last 16th and the first half of the 17th centuries,
surviving today, have a string vibrating length of between 0.57 to 0.59
m (24). With two semitones margin below the breaking frequency limit
suggested as venetian pitch standards of that period (450 ÷ 466
Hz), which seems to have kept rather stable in that time span (21), a
range of breaking points is obtained of between 33 to 36 , the assumed
pitch being ' for the chantarelle. Assuming an a' pitch
instead, the breaking point values rise to 38÷40 .. These
deductions represent yet another positive support to the table 1 data.
2. Iconographic
evidence
A general
characteristic
consequent to the loading of gut is that of requiring no particular
twisting techniques since the high specific weight increase, by
noticeably reducing the working diameter produces a remarkable decrease
in the string's stiffness. The strings keep a smooth surface, in
accordance with iconographic sources dating from the turn of the 17th
century a good emblematic example of which is represented by the
painter Evaristo Baschenish (1617-1677). He always depicted very curl
strings on musical plucked and bowed instruments, and the length of
string in excess and not in use,
bundled
up as though were of pliable cord (a detail not to be overlooked in
our investigations; our modern strings, on the contrary, besides being
impossible to bundle up in such a way without damage, they stick out of
peg boxes as straight as pins) and also always depicted them having a
smooth surface. Possible doubts about the accuracy in reproducing from
life can be cleared by a painting in Palace Pisani-Moretta in Venice:
besides the usual musical instruments whose smooth strings are clearly
visible, at one side, lying on a tambour, is a tailor's spool where on
the thread is a typical rope structure.
A second important
indication
coming from the 17th century iconography, is the colour of the lower
registers strings. It must be said incidentally, that colour can not be
taken on itself as a decisive confirmation of gut loading. In fact it
is quite possible to increase the weight of the material even
considerably, without changing the colour of strings to such an extent
as to be noticeable on a painting. Besides, some dyeing processes in
use in the 16th and 17th , especially for thin strings (see T. Mace and
J. Dowland) aimed for purely aesthetic results. In any case, in the
realm of the chromatically distinctions, iconography provides generous
and important contributions, especially when taken in relation to other
information available today. Thus low strings often appear to be
blackish, brown or red coloured, in short, colours which are totally
different from the natural colour of gut, and they begin to appear
exactly where the acoustic shortcomings of plain gut would make
themselves manifest.
The already mentioned
C. Mouton's
portrait, and that of the anonymous
17th
century lutenist in the
Kunsthalle, Hamburg are very good
examples (25). Red bass strings, starting from the 6th course down, of
apparently reduced diameters, suggest a use of colour which is not
aesthetic, but simply a consequence of loading process, obtained
perhaps with cinnabar, a heavy red mercury sulphide, which was an
abundant raw material in some areas of central Italy, the same, in
fact, where such a commercial type of bass strings were manufactured:
the "pistoys" (9).
As far as bowed
instruments are
concerned, the best among many example available are two paintings from
the second half of the 17th century by a Dutch painter in the German
National Museum in Nuremberg. In these works a number of plucked and
bowed instruments are depicted, probably life size, among which a
(bass?)
viola
da gamba and a
smaller one (soprano?) deserve special attention. Both instruments'
6th, 5th, 4th and 3rd strings, are fairly dark colour. The thickest
string being almost black, while the two top ones, much lighter, are
exactly the same colour of the frets.
Further details can be
noticed,
such as that they are perfectly smooth (on the bass viol's 6th string
it is possible to see light been reflected), while the apparent
increase in diameter does not follow the progression one would expect
at all in a situation of equal working tension if gut strings of equal
density were used. The
violin also
shows some very interesting aspects: while the first two strings are a
light colour, the 3rd and 4th are a dark colour similar to those of the
above described viola da gamba, bringing to mind J. Talbot's writing in
the early 18th century:
"...best strings are Roman 1st & 2nd of
Venice catlins: 3rd & 4th best be finest & smoothest Lyons, all
4 differ in size...". Lyons, as known, were a renowned type of low
register strings then available on the market. A confirmation of that
anonymous painter's colour fidelity comes from the cittern, whose
strings, again in accordance with J. Talbot, are a dirty yellow (brass)
while the two top courses are grey (steel). Another example like this
can be found in the wonderful painting
Concerto in casa Lazzari
(second half of the seventeenth century?) by Girolamo Martinelli
located in Carpi (Italy). In this painting, Martinelli depicts the
violone's third thorough sixth strings in a deep brown colour and the
higher two strings in white. On the
bass-violin
depiced in the same painting, the bottom two basses are again brown, as
in the violone, with the top two strings very light in colour and the
second string nearly so.
The last example about
violin came
out from a paint of
Rutilio Manetti,
Siena 1624 year, (Dublin, National Gallery).
3. Literary evidence
In the area of written
sources, a
passage in the Mary Burwell lute tutor (c. 1670) could not go
unnoticed. In chapter 16 dealing with two headed lute introduced by
English Gaultier, the author complains about the problems caused by "...the
confusion that the length of sound produce it alsoe..." and "...every
basse sound make a confond with every string". The above mentioned
two headed lute is the one depicted in the well known portrait of
English Gaultier and in many other 17th century Flemish sources. Such
an instrument may perhaps be identified with the lute made by Raphael
Mëst in 162..., now in the Linhöping library in Sweden, whose
extended string length is less than 90 cm (26), roughly in line with
the measurements given by J. Talbot for this type of instrument. At
such vibrating length such an overpowerful persistent sound, so to make
the anonymous author complain and lutenist revert to use lute without
extension, is in no way justifiable, for unloaded natural gut strings,
no in after what twisting method is adopted, which anybody can easily
verify.
Another source
deserving attention
is a report by
Claude Perrault:
(document 9)
"...c'est par cette même raison que la maniere
que l'on a inventée depuis peu de charger les cordes a boyau,
rend leur son beaucop plus fort: car le fil de metail trait..."
(27). The author refers to the new overspun bass strings giving however
the impression he is talking about a new technological strategy for
loading gut (i.e. the use of metal wire) in place of a more traditional
one.
As far as 17th century
lute
treatises are concerned, such as
Robert
Dowland's (18) and Thomas Mace (10) for instance, the most
interesting information (besides confirming more or less explicitly the
strings smoothness) is the subdivision of strings in classes according
to their specific use on the instrument. In Mace's treatise, for
instance, three classes are defined: strings suited only for treble
registers and the higher basses octaves (Minikins, Romans), strings for
mid-range registers and the other basses octaves (Venice catlins) and
finally strings exclusively used for basses (Lyons, red Pystois) (28).
This "acoustic specialization" of strings induces to get over the idea
of just one manufacturing system, in favour of a complex technological
diversity, indispensable to grant a finished product possessing the
acoustical and physical features necessary, from case to case to obtain
maximum tensile strength for trebles, high elasticity for middle
registers and high specific weight for basses.
Such a diversity could
be achieved
by the string makers of the time both by introducing new twisting
techniques and by merely "chemical" means suited to increment, as much
as possible, the acoustic disposition of natural material. Among this
methods the use of aluminium salts (29) deserves mention, and above
all, the sulphuration process, a millenary silk bleaching technique,
also used by the anonymous Paduan string maker from the first half of
the 17th century mentioned by Skippon (30), which seem to go well
beyond the function of merely bleach the material, which is achieved in
a matter of a few hours, any way. Instead the ancients kept this
operation going for days, even; one could suppose a function similar to
vulcanization of rubber, causing a loss of plastic properties in favour
of elastic ones (31). A partial answer to this question will perhaps
come from the results of chemical tests under way, which aim at
verifying weather sulphur can actually fix itself into the collagen,
the basic stuff of gut, thus building up disulphide links between the
proteid filaments.
4. Experimental
tests
The actual making of
experimental
loaded gut strings (32) went through a complex phase of quality
standardization, which also included a careful study of treatises about
dyeing and tanning of leather in use in the 16th and 17th centuries
(33) and a long experimentation, through a some hundreds of tests, with
such ancient dyeing and tanning baths (but obviously avoiding any toxic
product). These experiments allowed us to discover the peculiar
characteristics of the new strings, which could be then related to the
historic information in our possession.
The specific weight
reached was
about 2.90 , i.e. 2.3 times the density of plain gut which corresponds
to a diameter 34% smaller than plain gut strings and 40% smaller than
rope-construction strings, thus perfectly compatible with what was
measured on the bridges of the examined historic instruments.
The tone of the so
obtained
strings, as was to be expected, was rather dark, fundamental-heavy,
bringing back to mind the only record in our possession by the English
poet Edward Benlowes (1603-76), of how bass strings of the past might
sound (34). A tone, in short, lacking a good part of the higher
harmonics, which was to be made up for, at least as far as the lute is
concerned, by the use of octave strings. It was however perfectly
coherent with the "personality" of the higher untreated gut strings,
achieving a natural extension towards the bass, unlike what
unfortunately happens with overspun strings, which from the very outset
suffered from serious tonal dishomogeneity (35).
The smaller diameters
(especially
those smaller than 1.0 mm) showed, on the other hand, such a harmonics
rich tonal response as to dispense with the need, for the lutes 4th 5th
and 6th courses, for octave strings, in favour of a unison arrangement.
It is curiously significant to notice how the use of stringing these
courses with unisons began to spread roughly at the same time the
custom of tuning the 7th course a fourth below the 6th came into use,
and more in general, with the extension towards the bass in the late
16th century, first hints probably of a the availability of a new type
of string. An iconographic hint to this may perhaps be found on the 7
courses lute in Caravaggio's "I musici", c. 1594-6 in the Metropolitan
Museum of New York, where only the 7th course is a vaguely reddish
colour.
Where extended neck
come into
play, owing to the reduced diameters, a rather bright and persistent
sonority was achieved, enough, that is, to cause the problems the Mary
Burwell lute tutor's author complains about. The tone on the other
hand, became rather nasal. Used as bass strings on neck of limited
extension, such as an eleven course baroque lutes for instance, the
sound acquired a certain dark gravity almost percussive, which coupled
in a perfectly homogeneous manner to the sound of the octave, also made
of gut.
Tests carried out on
bowed
instruments (violins, viola da gamba, violone and double bass) confirm
essentially what already experimented with the lute, and suggested also
to reduce, even substantially, the amount of loading for mid range
strings (violin 3rd and gamba's 4th) which sounded too bright. It was
not necessary on the other hand to change the working tension normally
in use. The breaking point instead, because of the loading process,
underwent a decrease of 20÷25% compared to that of untreated
gut, a minor problem for low register strings, which work at only a
fraction of their total tensile strength. Anyway, the acoustic features
shown by these strings inevitably led us to reconsider, for bowed
instruments, the criteria for post positioning, hairs breadth and
tension and the type of bow to be used. For today lutenist, they
dispense to constantly stopping overspun strings in order to avoid
unwanted dissonances.
5. Conclusions
The contributions
given by each of
the disciplines examined and the iconography, from which only a few
examples among many have been mentioned (36), historic documentation,
original bridges measurements, and practical experimentation, allow us
to draw a rather clear picture and, we believe, a convincing one. To
confute the hypothesis of gut loading, the only alternative is to
maintain that the basses of the lute -whose bridge-hole diameters were
recorded- worked at a tension between 1 and 2 kg. I leave it to the
reader to judge the credibility of such a theory, maybe after trying to
play a lute with basses set at such tension.
However, we should not
forget that
the heart of the matter lies in what plausible answer alternative to
gut loading can satisfy the evidence? Or should we really believe it
possible, in the face of hard facts, that a thick unloaded plain gut
string, at a working tensions of less than 2 kg, could actually produce
a satisfactory sonority in lower registers without sounding like a
rubber band? As far as lute bridge-holes are concerned, we believe that
they can be taken as proof. Such research has been extended to the
talpieces of bowed instruments, although originals are hard to find.
The bridge and
tailpiece-hole
diameters found on original instruments factually represent a universal
yardstick employed undoubtedly by the luthiers of the past to fit any
sort of gut bass strings then available on the market. Thus the
technological matrix common to Lyons, Pistoys, and
Dowland's Catlins can only be identified with the loading of
gut.

23) For every standard
of
frequency taken by considerations, attain the corresponding f'
frequencies of top string. Two semitones above of these, there are
respective breaking frequencies. The product with the vibrating length
give us breaking index K that for breaking point of 32 is equal to 246
.. By a no complicate proportion, we can obtain every breaking point.
If the interval between working frequency and breaking frequency is
equal to a single semitone, breaking points will change between 28 and
35 ; 34÷39 if this margin is three semitones.

28) A painting by
Louis de
Sylvestre (portrait of a lutenist at Saxony court, ca. 1724) represents
an interesting iconographic support of Mace indications. The strings of
courses from I to IV and the octaves of courses from VI to VIII have a
blue colour, the V course and the remaining octaves (it was an 11
courses lute) have a white colour, besides the bass strings of courses
from VI to XI all have an orange colour. The Talbot violin as well
follows strictly this track: high range Romans, mid range Venice
Catlins, bass range Lyons.
29) According to
Labarraque
(Antoine Germain Labarraque: "L'art du Boyaudier", Paris 1822,
Biblioteque National Paris) the function of aluminium salts is to
facilitate the sedimentation of the ashes used in alcaline baths
employed to degrease the fresh gut.

there is a
curious recipe to make harmonic strings: "Take the tendons of a
horse's back which you will have pounded in a cloth with a wooden
mallet until they become soft, then have them twisted well together
with animal glue. Then dried them and they will be very strong and good
strings and they will been almost of silk..." Don Thimoteo
