These Mixed Glass Rectangles are a fantastic mosaic material. Made of clear molded glass with the colour fused onto the bottom of the tile, they create depth within a mosaic. The tiles have a completely flat face and rounded edges, and are easily cut with wheeled glass cutters. Suitable for indoors and outdoor use (but keep out of direct sunlight as they may fade). There clear glossy surfaces polishes up beautifully after grouting. Sold in packets of 115gms (approximately 50 tiles), they range in size from 1.5 to 4 cm's and 4 mm thick (the same thickness as a standard glass mosaic tile).
