Hi Guys,
Winter here in NZ. Working outside (5deg-8deg C),trying to move surface figure, of my current, (on bench) 22" mirror, in the right direction. In this temperature range #55 G is too hard. What do I need to do
to soften it, to be like around an equivalent to #44 G. In the old days, (50 years back) when I used a resin instead of pitch, we used pure turpentine, and beeswax to "condition/temper" the resin for the lap. Can I use turps, or do I need some other substance to do this, (and about what quantity of additive is needed per KG of Pitch?)
