Well I have the bismuth sitting here, and have been working on egg molds. I've been trying to do it in a half-assed manner and surprise surprise, I've learned several important lessons in what not to do.

Getting the positive image of the egg in paraffin has proven easy. Well easy since I'm not after a whole egg my vision is a little different. I'm not positive if cutting the top off or cutting an angel off will work better so I'm trying both. 

Getting the halfway mark on the egg has proven a little more challenging

I'm going to have to break down and get some modeling clay, and possibly some RTV. In the meantime I'm waiting for the IR thermometer to arrive.
