The machinability of fluor-mica glass-ceramics is an attractive characteristic of these materials. However, the poor mechanical strength and hardness has limited their applications. In this research, to overcome this problem, a glass frit in the system CaO-SiO 2 -P 2 O 5 -MgO was gradually added to
## Abstract The purpose of this study was primarily to determine the feasibility of heatβpressing a micaβbased glassβceramic with the use of commercially available dental equipment, and secondly to evaluate the effect of various processing variables on the degree of crystal alignment in the pressed
