It is a heat-resistant glass pendant featuring a mysterious three-dimensional pattern. I imaged galaxies and nebulae floating in outer space. The appearance of shine and pattern will change depending on viewing angle and light source. I expressed the color of the pattern using gold and silver. I use blue glass on the back side of the glass. When you hit a bright light on a three-dimensional pattern, the pattern shines beautifully in a glass work. It is a glass pendant made with handmade, melting heat-resistant glass with oxygen burner that uses oxygen more than 2000 degrees. The heat-resistant glass used for the material is harder and more transparent and beautiful than ordinary glass. It is antioxidant, it is characterized by being light and difficult to discolor and deteriorate. 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 triple twisted string) It is a black wax code. Since the string has a stopper, you can adjust the length of the string by sliding the stopper. This work seems to cause a change in the appearance of coloring etc. depending on the light source. The image is taken in an environment under sunlight. Image processing is not carried out. I am handmade and carefully manufactured, but please note that it is not a perfect circle or spherical shape. We do not accept returned goods due to reasons such as design, so please check the image and feel free to contact us if there are other unclear points.
