The crackling itself, also known as crazing, isn't something you can fix. When you run your hand over crazing, it should be relatively smooth. Any actual cracks or chips are considered damage and should be professionally repaired. ... Crazing is caused by the glaze being under too much tension.

Is crazing reversible?

The production of crazing is a reversible process, after applied compressive stress or elevated temperature (higher than glass transformation temperature), it may disappear and the materials will return to optically homogeneous state.

How do you get rid of crazing?

Crazing can often be eliminated simply by applying a thinner glaze coat. With some glazes, a thinner coat is not an option, but often a slight decrease in glaze thickness will stop crazing.
