Abstract of the Disclosure This invention relates to the preparation of glass ceramic articles in which potassium fluorrichterite and/or a related fluormica constitutes the predominant crystal phase(s). The precursor glasses can be crystallized in situ very rapidly and exhibit very little thermal deforma- tion during the crystallization heat treatment. The base glasses are essentially free of Li2O and consist essen- tially, expressed in terms of weight percent on the oxide basis, of: SiO2 61-70 Na2O 0.5-3 BaO 0-3.5 Al2O3 2.75-7 K2O 2.5-5.5 P2O5 0-2.5 MgO 11-16 Na2O+K2O <6.8 CaO 4.75-9 F 2-3.25
