A random 1kg selection of black, white, brown and grey glass tiles; you will get a selection of finishes including the milky opaques, a few iridescent tiles, transparents, some gemme and the usual bubbly numbers.  A really economical way to increase your palette. 

Individual tiles mostly measure 20 x 20mm and are around 4mm deep but there will be some variation in depth. Tiles come loose in plastic bags and are almost all on paper backing so will need to be soaked off. Use Leponitt or other wheeled cutters for cutting glass tiles.
