Abstract

15,955. Green, W July 27. Pottery.-A material to be used together with fire-clay in the manufacture of ceramic materials is prepared by selecting igneous rocks, or in mixing them with chalky and siliceous materials, in such a manner that the proportion of K2O, Na2O, CaO, and MgO stands in a certain relation to that of Al2O3, Fe2O3 and Mn2O3, and SiO2 respectively. The material may either be mixed with the clay without further treatment, or it may be fritted first, the proportions differing in the two cases. Using the symbol RO for the oxides of the alkalies or alkaline earths, and R2O3 for the oxides of aluminium, iron, or manganese, the proportions to be used are, for the fritted material, 1 RO, 44 R2O3, 3À5 SiO2, and for the unfritted material, 1 RO, À625 R2O3, 5À0 SiO2. After admixture with clay the composition should comply with the following formula: x RO, y R2O3, 5y SiO2 where y equals from 2x to 3x.
