The nature of glass

Glass is a solid solution of metal oxides in silica. Large glass viscosity during cooling prevents the movement of molecules, and thus crystallization silicate compounds. Create a transparent glass. Its properties - fusibility, thermal expansion, mechanical and chemical resistance, hardness, gloss, transmittance and refraction of light - depends on the chemical composition.

Production and processing of glass

A mixture of adjusted and raw materials (glass strain), transferred to a gas furnace, where temperatures up to 1500 ° C melts to the thin enamel, which is clarified. To produce a small amount of glass used pan oven. Under the fireproof vault stand several fireclay basins, around which the gas burns. The handmade glass product are made this way. The glass masters gathers the molten by glass blowpipe and blowing gently creates a base ball. The size of the product is gaining more by enamel. During permanent rotation of a whistle will be created stock, which gets the final form by blowing into a wooden (soaked) form. After separation from the pipes product proceed to the cooling oven, where is getting cold for several hours, so the glass compared to internal tensions. Otherwise, the glass cracks. Sharp edges are resurfasing, or further refine the products to reach the form that we see.
