Zusammenfassung:	The solution falls into the field of epoxide resins and ceramic manufacturing. The decrease in the weight and increase in the mechanical resistance especially of the coatings of ceramic duplicators is solved. The mass, according to the solution, can be prepared by homogenisation of 100 parts by weight of plasticised epoxide resins, 5 to 30 parts by weight of filling agents and 10 to 50 parts by weight of polyamine, polyaminoamide, modified and additive hardeners based on aliphatic amines. The space in the prepared female mould of the part is filled by this not yet hardened composition and it is exposed to the hardening process at a temperature of 0 to 80 degrees C, to an advantage of 20 to 30 degrees C.
