If your glaze freezes, is it still ok?
What happens when glazes freeze?
Yeah, freezing is fine. You would definitely want to high speed mix your glaze after it has frozen, but freezing just affects the water. I would high speed mix and sieve my glaze if it had been frozen for a little while. But it’s not going to affect any of the glaze particles that are in the bucket.
Freezing really only affects the composition of the water. Water turns from a liquid to a solid. It’s more of a problem with clay bodies, because clay bodies rely on plasticity, which is related to the relationship between the water and the clay particles. And when water freezes in a clay body, that can break the magnetic bonds between clay particles and cause your clay to be short. But all it takes is some good wedging. A clay body just needs to be mixed really, really well after it has been frozen.
Glazes freezing shouldn’t really be a problem because it’s still in its liquid state. In the bucket, the water is frozen and then thawed, so the water is back to a liquid. And then I would just give it a really good mix and probably sieve, and on from there.
