Tiny post today. The end of the semester is throwing me a loop and keeping me busy. Here's the last step before actually pouring the molten metal into the molds.
Basically in this step, using a torch, the wax is melted out of the silica casing. One of the concerns in this is very nearly the same concern when attaching screws to the piece. When the wax is melted out, it's important to start from the bottom of the piece and melt the bottom of the piece so that the wax at the top has a place to go. If the bottom of the cup doesn't clear first, then the wax above it won't have anywhere to go and will expand and possibly damage the mold. Always point the torch down, and think through exactly how the wax will melt.
I've been thinking about posting about video production soon, but at the moment I am far to busy actually putting together my video projects.
