Our Kilnformed Glass Terrazzo Style Spoon rests and sushi plates are 100% handmade. Each Piece begins as raw sheet glass, which is cut to size. The terrazzo patterns are created by screenprinting ground up colored glass powders on the sheet glass and firing them in an electric kiln. Each piece is fired multiple times before being “slumped” into a sushi plate or cast into a spoon rest. Due to the fact that the designs are glass “fused” into the pieces, they will not fade or wear off over time. The items are food safe, but we do recommend hand washing.
