Crystal glass mosaic tiles are colourful and a beautiful tile to mosaic with. This tile is made from moulded clear glass which means that it has rounded soft edges and a completely flat face. The colour is fused to be the bottom of the tile which creates a lovely depth to the tile. Cut easily with wheeled nippers they can be used indoors and out, and are frost and fade resistant. Each packet contains 100 gms (approximately 16 tiles) and is 25 x 25 cm square and 4 mm thick (the same thickness as a standard glass tile).
