STUDY OF GLAZE PENETRATION AND ITS EFFECT ON GLAZE FIT: I‐III*

A bstract A method for determining glaze penetration was developed and the effect of glaze penetration on glaze fit studied. The effects of twenty‐four fluxes on penetration of a base glaze into semivitreous, hotel china, terra cotta, cordierite, pyrophyllite, wall tile, and steatite bodies were determined. The result shows that glaze penetration affects glaze fit and that penetration varies greatly, depending on glaze composition and the character of the body.
