Perhaps you just wish to play with making your own lube, but why don't you just buy some sticks of Alox from Javelina for a couple of bucks apiece, and melt them down in your pan?
I've done it that way for a whole lot of years, and it works great. I usually get a fired case that is slightly over bullet diameter to use as a cookie cutter to cut them out of the lube.
I imagine this should work with the silicone "pans" too.
Sounds like a bunch of unnecessary work, to me..
