Crystal glass is 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, refractive index and brilliance, but lower heat resistance compared to other types of glass. Due to the lead content and a certain selection of angles formed by the edges, crystal products are distinguished by an unusually bright, multi-colored play of light. They have a beautiful ringing.
