[ Gilles Chouinard asked in 150306 MMDigest, "Does anyone have
[ a source for Chatterton's compound?"
Gilles, Chatterton Compound was invented by John Chatterton around
1861. It was also known as "laboratory wax." You may be able to find
this reference:
NAVY MIL-W-3172A CANC NOTICE 1 WAX, LABORATORY (CHATTERTON'S COMPOUND)
The product was available in several grades and was pretty much
considered obsolete for new applications during the late 1980's.
I have not seen it available for sale in over five years.
The ingredients of this product are, by weight, as follows: one part
of Stockholm tar, one part of rosin, and three parts of gutta-percha.
[Also described as] a mix of 1 part of Stockholm tar to 3 parts of
gutta-percha (greyish- black latex) and 1 part resin. It forms a
plastic black insulating compound.
Many of the above names for the ingredients are the original and now
obsolete names.
Good luck,
