It is a heat resistant glass pendant featuring a spiral pattern of three dimensions. The color of the pattern was expressed in colors using gold and silver. Because it is a three-dimensional pattern, you can enjoy changing the appearance of the pattern of the work depending on the viewing angle. When a three-dimensional geometric pattern hits the light it appears to shine. I use black glass on the back side of the work. It is a glass pendant made with handmade, melting heat-resistant glass with oxygen burner that uses oxygen more than 2000 degrees.

It is glass which is mainly used in the field of physics and chemistry, optical. We will deliver it in the same state as on the image with the string. It is a string than a black one.
