Third up for the day was the same inputs as Batch 3, but Mineral Spirits as a solvent. I thought it was a dud as the top layer was hard, but underneath was the gold. I believe that using minerals spirits caused the wax to flash off a little and made the top hard as I left it to cool with the top off. Texture is granular like sand and very uniform. Interesting, Batch1,3,4 will be tested tomorrow and pics to follow
