boroccus UV light reaction 3D geometric pattern borosilicate glass pendant

It is a handmade glass pendant with a three-dimensional geometric pattern of fantastic colors using gold and silver made of heat-resistant glass borosilicate glass. You can enjoy the change in the appearance of the pattern depending on the viewing angle. The pattern shines beautifully when the glass is illuminated with bright light. It is the only glass pendant made by hand. When this work is illuminated with a black light (ultraviolet light), the patterned part reacts and emits a pinkish light. * (Not all patterns shine. The degree of shining depends on the intensity of the ultraviolet light.) There is also a video of this work, so please check it out. The second half of the video is a video shot using a black light. https://www.youtube.com/watch?v=82ntEk01Rvk The size of the work Length (including stringing part) Approx. 3.7cm Width (maximum part) Approx. 2.9cm Thickness Approx. 2.5cm. Weight Approx. 29g (including string part) Black glass is used on the back side. This is the only glass pendant made by hand by melting heat-resistant glass at a temperature of 2000 degrees with an oxygen burner that uses oxygen. The heat-resistant glass used as the material is harder and more transparent than ordinary glass, and is characterized by its antioxidant properties, which are resistant to discoloration and deterioration, and are lightweight. This glass is mainly used in the fields of physics and chemistry and optics. The pendant string will be delivered in the same condition as the work image. (It is a string from the black wax cord.) Since the string has an adjuster, you can slide the adjuster to adjust the length of the string. The work image was taken in an outdoor sunny environment and in an environment under LED lighting. The video was shot outdoors in the sunlight. There may be a difference in the appearance such as color due to the influence of the displayed device. We make it carefully, but because it is handmade, the shape is a perfect circle or sphere, the pattern is symmetric, and it is not the center. Please check the work image etc. We do not accept returns for design reasons, so please check the image and feel free to contact us if you have any other questions. Since it is a glass material, please handle it so as not to give an impact that may cause scratches or cracks. The delivery method is Yamato Transport Courier Compact.
