Frequently Asked Questions

How Do I Stop My Glaze From Cracking?

You can also add a little sugar or vinegar to your glaze to help stabilize it. And be sure to bake your pottery at the correct temperature and for the correct amount of time.

What Causes Glaze To Flake Off?

One cause of glaze flaking off is the application of too much glaze. When the glaze layer is too thick, it can separate from the underlying ceramic body. Another cause is the use of low-quality glazes that don’t adhere well to the surface of the ceramic. A third possibility is that the firing temperature was not high enough to properly fuse the glaze to the clay body.

Can You Refire Under Fired Glaze?

Yes, it is possible to refire under fired glaze. This is done by heating the piece to a temperature that will soften the glaze and then applying new glaze.

Why Is My Glaze Pinholing?

There are multiple reasons why a glaze may be pinholing. One possibility is that there is something in the clay body that is reacting with the glaze and causing the holes. Another possibility is that the glaze is too thin and is not adhering properly to the clay body. Finally, if the kiln is not firing evenly, this can also cause pinholing in the glaze.

Can You Layer Glaze On Top Of Glaze?

Yes, you can layer glaze on top of glaze. However, it is important to make sure that the glazes are compatible, meaning that they have the same firing temperature and are the same consistency (thick or thin). If they are not compatible, the layers will separate and the piece will be ruined.

What Causes Glaze To Crackle?

The cause of glaze to crackle is the thermal expansion and contraction of the glaze as it is heated and cooled.
