Very impressive, I really liked how low tech it all was (except for buying a high purity Si wafer but I can see why growing a crystal that size wasn't on the agenda). Nice to mention Jeri, that first 'cooking with Jeri' episode probably ranks as the all-time-high for makers in my book.

After refreshing several times to avoid logging in, the gGods decided to let the video play. I never knew that this class of thing existed: https://www.amazon.com/Microwave-Professional-Fusing-Melting...

Anyway, very cool home project.
