Re: [ATM] Gugoloz 64 (temper it with Guoloz 55?)

[Guy Brandenburg <gfbrandenburg@yahoo.com>]

The manufacturers say that this method (mixing
different gugolz numbers) is precisely the way to get
the hardness you want.

Personally, I am not crazy about the stuff. At the
Delmarva Mirror Making Workshop, it seemed like every
can of the stuff (all identical numbers) was
different.

There are lots of methods suggested of softening pitch
- one being use of turpentine, which I have used from
time to time. However, it may be that using turps sets
you up to have an outer layer that gets too hard,
because the turpentine evaporates from there.
Recommendations are to use beeswax or castor oil
instead.

Hardening a batch of pitch is pretty easy: just boil
it for a while. But pitch is really strange stuff!

I prefer the tempered pitch from willmann-bell. I
wonder who makes it for them.
