Abstract: Glass and glass ceramic compositions having at least a lithium disilicate crystalline phase, a petalite crystalline phase, and a residual glass phase along with methods of making the glass and glass ceramic compositions are described. The compositions are compatible with conventional rolling and float processes, are transparent or translucent, and have high mechanical strength and fracture resistance. Additionally, processes of 3D forming glass ceramic preforms having the glass ceramic composition discussed to produce glass ceramic articles are described. Further, the compositions are able to be chemically tempered to even higher strength glass ceramics that are useful as large substrates in multiple applications.
