So here’s a cool place to check out: Glaze21 exists. It’s a glaze archive, which you can find here and there on the interwebs, but this one’s better in three important respects:
1- It’s got more people sending in submissions than the other ones, which means more recipes, more testing, and much more commentary on success/failure/issues.
2- It’s searchable!
3- The plan is to eventually have colour photos of each glaze, on various clays.
I am enjoying having a poke through it.
