Thanks Sopticals re: mirror polishing

Thanks Sopticals. Will post pictures of my next stage, Polishing. What a black Art! I was using Tropical Resin Pitch from my Australian supplier. The first attempts had many bubbles. The second attempt with a higher mix of Castor Oil produced a much improved pitch lap which I used for an hour before it started breaking up and breaking off its plaster base. It was obviously still to hard and brittle.
I have since ordered some Gugolz Pitch #55 from GotGrit.com suitable to my current working temperature of 16C.
