Glass rondels are circular pieces of glass that have been formed into a disc shape. They can be blown or spun. Kokomo Opalescent Glass has a good description of the difference here. A rondel resembles the base of a wine glass, but it's more interesting. Because it is handmade, it will have swirls and bubbles that catch the light and make each rondel unique.
Glass rondels may be easily foiled or leaded, and incorporated into a larger work.
Our blown clear rondels are currently available in three sizes, 3", 4" and 6". Our spun colored rondels are 4" in diameter.
