Hand made fused glass coasters from my workshop in Derbyshire. The clear glass back is capped with black and white glass in a check pattern which have all melted together during the kiln firing process. The coasters are 8cm square, have rounded corners and edges and are smooth to the touch. On the back of each coaster are 4 rubber bumps to protect the surface of your furniture. These coasters will easily wipe clean with a damp cloth.
