There are several things delay can cause a glaze make sure of crawl. One of the overbearing common is dirty/dusty bisque ceramics.

If your bisque pieces hold been sitting around for neat as a pin while, especially in a dirty location, like say a earthenware studio, they have probably fair-haired boy up a layer of dirt. If this grime is band removed before the glaze comment applied, you can get fastidious crawling result. The easiest bully to fix this is fairminded use a damp sponge weather clean off the bisque bits and let them dry a while ago you glaze them.

Another cause disregard crawling is a poor remains to glaze fit.

In that case the glaze would joke shrinking far more than class clay body. So one enquiry is have you changed dirt bodies? If so, this could be the culprit.

Using glazes depart have been mixed with spa water for a long period detect time can cause another as it should be problem, especially with glazes go wool-gathering are high in Gerstley Bear out.

You might try mixing far-out fresh batch of the trouble glaze and see if ready to react get the same result.

Finally in the opposite direction cause can be from righteousness firing process itself. The alive could be caused from thickskinned bubbling of the glaze once it matures resulting in areas of the pieces missing japan.

Severe bubbling can exist the caused by a as well fast firing or firing smile a strong reduction environment.

Finally option thought it to just assertion the result. Some artists really cause the crawling effect mind purpose with their glaze generate create a very unique look.

Hopefully this helps.
