Frequently Asked Questions

  • How do I know if a glaze will work with the clay I have?

    It's crucial that clay and glazes be matched for firing temperature. Both low- and mid/high-fire clays can bisque at cone 04, but the recommended glaze firing range will be different for each. Glazes need to mature in the recommended glaze firing range for the clay. Fire the glaze too low and it won't mature, too high and it may discolor or flow too much. Fire the clay too low and it won't vitrify enough to be durable, too hot and the clay will soften and distort or may even melt. Also, we always recommend firing test tiles to verify that the glaze is a good "fit" for the clay. Most of the time commercial glazes and clays work together, but it's still possible for them to not have the same rate of expansion and shrinkage, which can result in glaze crazing or shivering.

  • Can I fire these glazes hotter than the suggested temperature?

    Many glazes can fire hotter than the specified firing range, but the glaze will typically flow more, and certain colors may fade or darken. Consult the manufacturer's guidelines to determine whether the glaze you have in mind can take a hotter firing and be prepared to fire test tiles to make sure you know what to expect before applying to actual ware.
