Thank you for looking. I fired glass for stained glass (Bullseye) in an electric kiln. The size is around 10mm. Please use them as handmade parts! You are welcome to sell accessories etc. made using these items. Also great for summer vacation craft projects! I make these at home. I inspect them, but fine dust or debris may sometimes get mixed in. Please refrain from purchasing if you are sensitive to such things. Also, as I select them by hand, occasionally nuggets of different sizes may be mixed in. Some nuggets may have release agent remaining on the back, or black spots from firing. Please check the images for size and color. *As these are glass products, they may break if dropped or subjected to strong impact. Please understand the nature of glass and purchase at your own risk. Please check the images for size and color. Feel free to ask any questions!
