FIELD: medicine, stomatology. SUBSTANCE: composition consists of two layers and each has silicon dioxide, titanium dioxide, aluminium oxide, boron anhydride, potassium oxide and sodium oxide. The first layer has additionally calcium oxide and the second one has additionally calcium oxide, magnesium oxide and iron oxide and components are taken at the definite ratio. The composition exhibits high strength due to decrease of ceramic mass caking point and retention of high technological properties. EFFECT: improved quality and properties of the composition, decreased cost and availability of the material. 1 cl, 3 ex
