Mold release spray
Is there something you can spray into an embedding mold to make it easier to extract the solidified wax block?
I faced the problem of mold-release spray several years ago by mixing a solution of 5% green dishwashing soap (such as
Palmolive) in 50% Ethanol, then putting it into a pump spray bottle (available form any housewares department). This worked AT LEAST as well as the outrageously expensive stuff sold as "Mold-Release Spray", and it contained no CFC's or other "evils".
