    摘要: A process for producing feldspathic sanitary ware and the end product are disclosed in which a fluxing amount of a glass frit is used in the ceramic slip used to cast the sanitary ware. The frit contains both deflocculent oxides and flocculent alkaline earths which are leachable from the frit when it is placed in the ceramic slip. The deflocculent oxides counterbalance the effect of the flocculent alkaline earths to the extent they are respectively leached from the frit upon dispersal in a ceramic slip and maintain the slip at a workable viscosity. Upon casting and firing the slip, the present frit precipitates fine crystals of diopside having an average particle size of less than one micron which are particularly useful in lowering the firing temperature of feldspathic bodies by promoting the required degree of vitrification at lower temperatures than heretofore possible.

    摘要: This invention relates to the use of AlF.sub.3 as an opacifying agent in an opal glass making batch which contains 40 wt. percent or more of container and sheet glass cullett. The batch consists essentially, in weight percent, of 40-85% cullett, 0-25% Na.sub.2 B.sub.4 O.sub.7.5H.sub.2 O, 0-12% CaMg(CO.sub.3).sub.2, 3-19% SiO.sub.2, and an amount of Alf.sub.3, which is 10-30% of the weight of the cullett.
