I use Rapine Mold Lube. It's a black paint like substance I purchased about twenty years ago. I have a crafter's paint brush and I paint the entire inside of the mold. Then I smoke it with a candle real good.

As for the lead I heat it real hot. I want it to be hot and shine. To test the temperature I dip the corner of the mold in for the count of ten real slow. Lift the mold up and it lead should not stick to it, or you can light tap it and make it call back.

Then I put a chunk of candle wax in the molten lead and light it. After the flame burns off, I have a tin scraper that I pull all the sludge to the side and lift it out.

I also use a ladle to get my lead out.
