[ATM] Softening Gugolz

[Polk, Tom]

Hello,

I know you asked for experts but I'll chime in with my experiences:

Mineral Spirits = Works great. Adjustments to temper must be made in
small increments; no boiling off. Not smelly. Cheap, found at most
pharmacies.

Bees Wax = Not so good. The viscosity is not "linear" with temperature
change, small changes in room temperature greatly effect pitch temper.
Marked off my list. CeO acts different with lap. Subjective I know but
for the one time I used it the CeO did not embed in the lap easily.
Found at art stores, used for candle making.

Castor Oil = same as mineral spirits just harder to find (at least for
me). More expensive for unit of measurement than mineral spirits, but
still relatively low cost, found at most pharmacies.

Not on your list but turpentine = forgiving, boils off if you overshoot
temper, if polishing/figuring runs into months pitch temper can change.
Not to bad if you plan on a lap re-pour. Smelly, but I like the smell
(wife does not). It holds special place in my heart ;-), it was my first
tempering agent.

Over the years I have seen mention of many ways to soften Pitch

1) Mineral Spirits
2) Bees wax
3) castor oil

Well someone asked me for help... so before I answer them I want an idea

what all the experts thinks...
(psst if you have done it (poof) you are an expert :) )
