About the process of obtaining crystal
To get crystal, you need to melt the charge from which the crystal is made. The feedstock is melted in furnaces at a tremendous temperature of over 1500 degrees Celsius. After the product is blown out and given the required shape, it enters the furnace for annealing. Annealing is intended for more uniform cooling of the crystal. Further, in the flame of a gas burner, the upper part of the product is cut off. After that, the product undergoes the first quality control: are there any large bubbles, stones, curvature of the leg; measure the thickness of the glass layer.
Smooth products are adorned with a diamond cut. To begin with, markings are applied to the product, after marking, the product is placed on the conveyor and goes from master to master. After application, the diamond edge becomes matte. To obtain a transparent facet, the product is subjected to chemical polishing in a mixture of hydrofluoric and sulfuric acids. The acid corrodes and polishes the glass. Next, the product is thoroughly washed, and, if necessary, the edges are applied, which should remain matte. Finally, the product is tested again, marked and packaged.
