It is a handmade glass pendant designed to melt heat-resistant glass using an oxygen burner and to be designed in a three-dimensional geometric pattern. The color of the pattern was expressed by using gold and silver. The brightness changes depending on the viewing angle and the light source. A glass work that shines beautifully when a three-dimensional geometric pattern hits the light. We use black color glass on the back side. The heat-resistant glass is melted by the oxygen burner which becomes more than 2000 degrees using oxygen, and it is only one glass pendant made by hand. The heat-resistant glass used for the material is characterized by its hardness and high transparency compared to general glass. It is characterized by being antioxidant, lightweight and resistant to discoloration and deterioration. It is a glass mainly used in the fields of science and chemistry and optics.
