Same glaze, same clay, same cone 6 electric firing. Why is one speckled?

Thursday 16th June 2016

These are jiggered lids made from Plainsman M340 middle temperature stoneware. The one on the right was sponged in the dry stage to smooth issues that occurred during jiggering. That has exposed speck producing particles that were under the surface. This body is made from quarried materials that are ground to 42 mesh.
