Thank you for viewing! These were made by firing expensive dichroic glass in an electric kiln. They are approximately 4mm in size. Please use them as handmade parts! You are welcome to sell accessories, etc. created using these. ^ ^ I make these at home. I inspect them, but sometimes fine dust or debris may get in. Please refrain from purchasing if you are concerned about this. Also, because they are selected by hand, nuggets of different sizes may occasionally be mixed in. Some nuggets may have mold release agent remaining on the back, or black spots that occur during firing. Please check the images for size and color. *These are glass products, so 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! Thank you. #Nuggets #Glass #GlassNuggets #DichroicGlass #Handmade #Parts #Fusing #ResinInlayParts #SeaGlass #SeaGlassArt
