A detailed study by the method of quenching of ten closely spaced compositions in a small portion of the ternary system $$MgO-Al_{2}O_{3}-SiO_{2}$$ has delineated the tiny field of sapphirine and located the temperatures and compositions of three ternary reaction points. Sapphirine crystals are stable in equilibrium with a liquid in the ternary system only over the narrow range of temperature between 1,482° and 1,453° C.
