Guess what! I'm coating them in resin now which means they are ULTRA DURABLE AND SHINIER THAN EVER. I still have one of the old glaze-coated ones and it's held up well, but some people have had them get grubby. And the resin is soooOO much shinier. Gosh, these things have come a long way since I started making them around 2007.
I haven't tested this on beads yet but a lot of people are still interested in them, so I'll see what I can do. Life's been kinda CRAY lately.
