A bstract Experimental low‐temperature viscosity data obtained by the fiber‐elongation method are presented for simple three‐ and four‐component alkali‐alkaline earth‐alumina silicate glasses. In this study, soda, potash, calcia, magnesia, strontia, baria, and alumina were systematically substituted molecularly for silica and each other. A wide range of compositions was studied, including most commercial silicate glasses. Factors, formulas, and charts derived from experimental data are presented that predict the viscosities of soda‐lime‐alumina silicate glasses within about 1%.
