Kali aluminium silikate mineral leucite is a component of odotic porcelain. Porcelain is used in stomatology, producing unnatural teeth and renewing tooth structure. Purpose of this work was to get leucite by crystallizing modified alumosilicate glasses and by synthesizing kaolin in a high temperature. In synthesis of glasses were used these compounds: SiO2, AI2O3, K2CO3, CaCO3, TiO2, ZnO, Li2CO3, Na2CO3. Getting leucite from kaolin, as stock was used: kaolin, Al2(SO4)3, K2SO4. Crystallization of glasses was processed in 900˚C - 1100˚C and the time of exposition was from 2 till 15 hours.
