A bstract The devitrification characteristics of the field of compositions, which includes the commercial lime crystal glasses, were investigated. Tridymite was found to crystallize from glasses containing as low as 62% of SiO 2 . Tridymite, devitrite, diopside, sodium disilicate, and an unidentified compound were found to be primary phases. Potassium oxide (K 2 O), in general, lowers the liquidus temperature when it replaces Na 2 O.
