The influence of various structural factors on the translucency of an unglazed porcelain body was studied. These included (u) total concentration of crystals, (b) relative proportions of quartz and mullite, (c) refractive index of the glass phase, (d) its degree of iron coloration, and (e) content and size of voids. Porcelain bodies in the compositional vicinity of a 50% clay, 25% flint, 25y0 feldspar base body and corresponding simulated bodies composed of suspensions of mullite and quartz mixtures in liquids were studied. Translucencies of several representative commercial bodies were also measured.
