Crystal glass is a lead-silicate glass containing 13-23% lead oxides and up to 17% potassium oxides. Crystal glass is used to produce high-quality tableware and decorative items. It has increased density, transparency, refraction and gloss, but less heat resistance compared to other types of glass. Due to the content of lead and a certain selection of angles formed by the edges, crystal products are distinguished by an unusually bright, multi-colored play of light. Have a nice ringing.
