Actually, Melinda, the "defect" looks pretty cool to me. I would record everything you did to get that look even though you weren't trying. Then I would try to find another glaze with the same color and start testing again...You did run some tests on this glaze, didn't you?

Looks like the glaze is shrinking too much for the claybody. Were there fine drying cracks in the glaze before firing? Do you have the glaze recipe and if so can you post it?

I'm thinking this is related to the application to raw clay, like there's something going on with the clay being wetted during the glazing process. Have you tested the glaze on bisque? Commercial glaze, or did you mix it? Post the recipe if you mixed it.

If the defect is the blog of matting glaze to the left think it is a stirring the glaze properly defect.

I'm assuming the all over texture is meant....

Are you dipping or brushing ?g

Malinda is from Sri Lanka if memory serves? Which means laterite clay is being used. Typically laterite runs 32-40% alumina and 8-15% hematite= FeO3. It cannot be fired over 900C because the hematite content. Min- background info on the clay to help you figure out the glaze side. That said: I like the glaze effect myself, unique pattern.

If the defect is the small nearly bare spot about one third down from the top and just a bit to the right of the vertical center line, reapplication of some glaze and a refire probably should solve the problem.  Refiring has its own set of concerns such as glaze movement (excess running), body slump, color and texture changes, ... .

 

My guess is that the glaze was not adhering to  green ware at that spot.  Non-adherence could be dust, oily spot, finger mark, ... .
