I promised some videos of the lost wax process, so here goes:

This is the process of dipping the wax patterns (sculptures put onto a sprueing system–pathways for bronze to enter and gasses to be released).  The process involves coating the pattern with a silica-based slurry, then covering the wet surface with sand.  After it dries the process is repeated five or six times to build up a ceramic shell.

The next step is to burn the wax out of the mold, leaving a hollow shell:

After that I melt the bronze and pour it into the ceramic shell:

I’ll try to get videos of other parts of the process (oh, yes, there are lots more!), eventually.
