A bstract Lithia, as lithium carbonate, was substituted progressively for soda in the composition of a white cover frit. Substitutions were made on both weight and mol bases. Mol replacement of soda by lithia has resulted in improved fusibility, gloss, and opacity; higher gouge, surface abrasion, and acid resistance; and lower thermal expansion coefficient. Weight replacement has caused increased fusibility and gloss; a small decrease in surface abrasion resistance; marked decreases in opacity and in gouge and acid resistance; little change in thermal expansion coefficient, and a noticeable lowering of the transformation temperature.
