I'm so proud to have a store here that features only 'Handmade' American crafts and Art! Borosilicate glass is my medium and all glass that I use is handmade in America! All of my glass pendants are totally made by me in front of a sculpting torch and are free-hand molten glass one of a kind art pieces. They are then kiln annealed over a 24 hour period at temperatures over 1054 and then gently cooled to take out all the stress in the glass for lasting durability! Sometimes I add Gilson Opals for a dash of WOW! I hope you love wearing your cbottrun Pendant as much as I love making them!
