ABSTRACT:
Disclosed is a method of producing hard glass-ceramics from a melt of basalt enriched with one or more of CaO, MgO and SiO.sub.2 to achieve defined ratios of certain oxides in the batch, cooling the melt to a glass and thermally in situ crystallizing the glass to a highly crystalline glass-ceramic product containing a diopside solid solution as the principal phase.
