GC Initial LiSi Press is a high-strength lithium disilicate ingot with proprietary HDM (High Density Micronization) technology that equally disperses micro-crystals—rather than traditional larger-size crystals—to fill the entire glass matrix, resulting in excellent physical properties and aesthetics. It has a biaxial flexural strength of >500MPa and virtually no reaction layer when divested. The material is wear resistant, stable after multiple firings and optimized for use with GC Initial^® LiSi veneering ceramic and GC Initial^® IQ Lustre Pastes NF.
