Recipe/availability for Repousse Pitch paul_bilodeau1 02-07-2008

I am trying to find information about making Repousse pitch. I have
found several "recipes" for making pitch, but, most of them are from
the early 20th century when materials weren't covered by MSDS sheets
and "bad for you". Everything that I have found generally refers to
"Shoemakers Pitch" or some other type that is impossible to find.

Does anyone out there know where there is a common type of pitch that
can be used for the Repousse recipes as a backer?

Just in case you want to suggest it, I HAVE found a company that
carries red German Pitch but it is over $200 for a lump that won't
quite fill an 8" diameter bowl. Seems expensive to me.

Thanks,
Paul

First find on Google list for "repousse pitch":

# 6 parts chaser's pitch, 8 parts plaster of Paris or brick dust, 1
part linseed oil or tallow. Source: Metalworking Techniques for
Craftsmen by Oppi Untracht.

# 4 parts roofing tar (the kind roofers melt in tar kettles), 3 parts
pumice powder, 1 part turpentine, 1 part linseed oil. Melt tar in pan,
stir in turps, add pumice. Let a small amount cool and adjust amount
of linseed oil to get desired consistency. Source: My own recipe.

# Equal parts of beeswax and plaster of Paris. This is good for very
thin, fully annealed non-ferrous metal worked shallowly. Again, my
recipe.

When mixing any of the recipes for pitch, remember that some or all of
the materials may be flammable and take appropriate precautions with
regard to open flame, etc. It's a good idea to keep in mind that hot
pitch sticks to you and keeps on burning much longer than is bearable,
too.

Bruce,

Thanks for the recipes, but, I already have them. The problem that I
am running into is finding any business that carries (and sells)
chaser's pitch OR the roofing tar listed in these recipes.

Know of any handy sources?

Paul

Roofing tar has been an asphalt "tar" for at least the past 40 - 50
years and I suspect that is what is intended.
I have no idea where you are but can you try some roofing contractors.
Certainly they would know where some could be obtained, it is still
used.
