Hi everyone. I'm a bit new to pottery (self-taught so far, though I'm about
to take classes), and I have a question about glazes. I've been working in
earthenware clay up until now, and have recently decided to switch over to
stoneware as I'm getting more serious about pottery. The problem is that I
have a lot of low fire glazes that I would hate to waste. So is there any
way to use low fire glazes on stoneware? If so, how would I go about doing
it? I have yet to test (I have some tiles made up for testing the glazes,
but they aren't dry enough to use yet), but I was just kinda wondering what
to expect and see if you guys could point me in the right direction.

Roger,
Throw a bunch of stoneware small cups or bowls and test each of your
low fire glazes on them. I have used low fire glazes on stoneware with
no problems for years. Most of it on non functional pots. Some will
craze visibly others will craze but you can't see it with the naked
eye, but will most likely still be there. The biggest problem will be
the use on functional ware, they will seep water like in a flower vase.
Interior liner glazes for functional ware will take some more testing
to get a tight fit. Test, test, test! Good luck, Mike Gordon

Hi Rodger,
Assuming you know what the recipes are - and there is no lead - you can dry
them out and use them as a material in higher fired glazes.
If you use calculation - then add the glaze to your materials table as a
material and you can get where you want to be almost instantly.
If you want to use them wet - again assuming there is no lead - you can add
silica and alumina till they work right - start with a cup of glaze and
start adding the refractories till they work at a higher temperature - If
you have kept track of what you have added you can adjust the whole batch
when you get something you like.

Hi, Rodger,
I can only tell you the little I have learned. The hard way, mostly myself.
Hold on to your low-temp glazes: you will use them for a special project some time in the future. Water heals everything. I didn't understand the drying part.
I (personally) would start by ordering two pre-mixed glazes you like, maybe three. Order them dry. Standard ceramic Supply in Pittsburgh is a really good one for that.
Just take your time to use the glazes until you like what you see on the pots - until you feel you get the GLAZING results/technic you want. Don't let anyone make you feel guilty about that!
They have both cone 5/6 and cone 6 glazes. i can tell you which i like,but that doesn't help you.
Then, next, order the chemicals for two or three glazes you are interested in. maybe a recipe from a friend, or something you physically saw, or from the archives. Great recipes there. Work with that. test, cross-dip/brush/spray, the game.
THEN start playing. Playing is important but expensive.
Now, i am the one who cried "HELP ME" this weekend, but i've always been a much better teacher than a student. When you succeed, please teach me? :)
