Abstrakt:	Petrographic study of the refractory performance of silica-bonded investments revealed that recrystallized silica bonds consisting of tridymite and cristobalite are formed during burnout. The major reaction product created during casting is eskolaite. Liquefaction and sintering in the investment at and near its interface with the casting plugs pores and may lower permeability.
