A bstract Data are presented on leadless glazes in which barium, fluorine, lithium, and strontium have been employed as fluxes. Molecular and batch formulas are given for the best glazes with the test results from plant trials conducted in seven vitreous and semivitreous dinnerware plants. The glazes were developed for practical plant production as to cost of preparation, ease of application, and length of firing range. Tests include autoclave, thermal shock, impact, chipping, modulus of rupture, glazed‐ring compression, and scratch hardness.
