Abstract: A silicate-based composition includes, in mol.%: 35-65% SiO2, 20-40% CaO, 10-30% Na2O, 0-15% TiO2, >0-15% Al2O3, 0-10% P2O5, 0-15% ZrO2, and 0-3% SnO2. A method of forming a silicate-based composition includes ceramming a silicate-based composition such that the ceramming is a cycle has a first portion and a second portion, with the first portion conducted at a first temperature for a first time and the second portion conducted at a second temperature for a second time.
