Feldspar Glazes
Quite simply, glazes high in feldspar. Feldspar by itself melts well at high temperatures but it needs additions of other fluxes and silica to produce a balanced glaze that does not leach. The process of comparing the chemistry of a feldspar to a target formula for a typical medium or high temperature glaze, and adding materials to bring it into line, is quite fascinating. Since feldspar melts so well, it is common to find reactive glazes (ones with interesting visual surfaces) that contain high percentages, even up to 70%. However, since feldspar contains so much alumina, these glazes typically have almost no clay (since its presence would add alumina and destroy the active melting nature). That means they have poor slurry properties (e.g. settling, dusting, flocculating, running). These situations can be fixed using ceramic chemistry by supplying the Na2O/K2O from a low alumina material (eg. a frit) thus enabling an increase in the amount of clay in the recipe. Out Bound Links
