METHOD OF PRODUCING GLASS-CERAMITE Russian patent published in 2011 - IPC C03C10/00 C04B41/86 

FIELD: chemistry.

SUBSTANCE: invention relates to production of glass-ceramite used for external and internal facing of walls of buildings and other structures. The method of producing glass-ceramite involves preparing and batching crude components, mixing said components, moulding a substrate from the obtained mixture, forming a decorative layer on the substrate and roasting. The substrate is moulded from a mixture which contains the following in wt %: scrap glass 50.0-60.0; clay 20.0-25.0; vermiculite which is pre-expanded and saturated with liquid potassium glass 20.0-25.0. A decorative layer is obtained by fire polishing the surface of the substrate until formation of glased film.

EFFECT: high uniformity of the substrate and finish coat of glass-ceramite.
