GLASS PRODUCTS DECORATION METHOD IN THE DIATRETA TECHNIQUE Russian patent published in 2019 - IPC B44C5/08 

FIELD: manufacturing technology.

SUBSTANCE: diatreta is the predominantly bell-shaped glass vessel with double walls with a gap: the vessel body is located inside the outer glass laced “grid” of cut through work. Diatreta includes the inner vessel manufacturing and the decorative parts, in particular, the grid and letters fixing thereon with a clearance, which are formed on the workpiece from small glass chips by the sintering, the produced decorative elements are fixed on the Diatreta bowl body imitating wax or clay workpiece, and filling with the porous heat-resistant mass, after which the internal clay or wax workpiece is removed, into the resulting cavity blowing the set of glass, which forms the Diatreta inner vessel, and which is soldered with the decorative elements bridges, after the product annealing, the porous refractory mass is destroyed. Glass lintels bridges made in the form of glass darts.

EFFECT: technical result consists in reduction in the Diatreta technological replica operations labor intensity, the wider range of drawings and the multi-color images creation implementation possibility.
