boroccus galaxy nebula 3D pattern & opal borosilicate glass pendant

This is a handmade heat-resistant glass pendant with an opal in a mysterious three-dimensional pattern like a nebula in a galaxy. The opal's shine and the appearance of the pattern change depending on the viewing angle and light source. Black glass is used on the back side of the glass. The loop part where the string passes through is made of dark purple colored glass. ・Notes about the glass design There are air bubbles near the opal and in other places. Please check the introduction photos and videos. If you have any concerns, please feel free to contact us. There is also a video of this work, so please check it out. https://www.youtube.com/shorts/9tRfyYlE7jE ・Glass size Height (including string threading part) approx. 3.2 cm Width (maximum part) approx. 2.5 cm Thickness approx. 2.3 cm Weight approx. 18g (including string part) ・Glass shape It has a shape close to a sphere. The back side of the glass is flat so that the pattern does not collapse. This is a one-of-a-kind glass pendant made by hand by melting heat-resistant glass with an oxygen burner that reaches over 2000 degrees. The heat-resistant glass used is harder, more transparent, and more beautiful than ordinary glass. It is characterized by its anti-oxidation properties, which make it less likely to discolor or deteriorate, and its light weight. It is mainly used in the fields of physics, chemistry, and optics. It will be delivered in the same condition as the image with the string attached. It is a three-strand string with black wax cord. The color of the string can be replaced with other colors such as navy. If you would like to change the color of the string, please let us know at the time of purchase and we will send you a photo of the other string color later. The string has an adjuster, and you can adjust the length of the string by sliding the adjuster. The photos and videos of the work were taken outdoors in a sunny environment. This work is handmade. The shape of the glass is not a perfect circle or sphere, and the patterns are not perfectly centered or symmetrical. (We try to make the glass as balanced as possible.) We do not accept returns due to design reasons. Please check the photos and videos. If you have any questions, please feel free to contact us. Since it is made of glass, please handle it carefully to avoid impacts that may cause scratches or breakage. International shipping will be shipped by Japan Post Small Package Registered Mail.
