I can see why people find one or two glazes they like and just do everything with those.
But that would be too easy......
Testing glazes means a lot of stirring, sieving, dipping, drying, labeling, shifting buckets around, making notations on my test record pages.
Some tests were about new glazes; some were just checking old ones that might have changed over time.
I used to make my tiles really small because I put a string through the hole in the top and tie the tile to the glaze bucket. If the glaze is in a jar, I fasten the tile to the side with a big piece of transparent package tape.
I also use a Sharpie to label the bucket or jar in big letters. Saves a lot of time when you're trying to hunt down a glaze.
Bigger tiles mean more room for notes. I use any underglaze to do this. Just a dot on a piece of paper or spare yogurt lid is fine and handy for the underglaze. I also like the fine limner brushes to do the lettering with.
----------Of course, just as soon as I wrote this and fired the kiln, the thing overfired. The thermocouple failed. Pots welded themselves to the shelves and the witness cones are beautiful, pearly puddles.
A trip to Clay Art Center is in order. New shelves, new thermocouple, and while I'm at it, some grinding stones.
Pottery: It teaches you how to deal with failure and move on.
ALL the time.
