Thanks for all the replies, guys. Looks like I'll have to get some more plastic and then incorporate your suggestions. Bojon, if it's not too much of a bother, I think I'll take you up on your offer. I'm trying to figure out how to horizontal-dip using a microwave. A pyrex dish maybe? I bought some aluminum rod and bent it at a 90 degrees. Seems like that should work. I don't know about temp control with the microwave method, though. Seems like there'd be an awful lot of reheating involved. Usually when I pour, I just work with 2-4 oz. batches.
