This Italian smalti from Orsoni is sold in 100gram bags which contain approximately 35 pieces. This will cover an area of 8cm x 8cm (if you're feeling ambitious, you will need around 1kg to cover 25cm², and 16kg to cover 1m²). The pieces are hand-cut and therefore quite variable in shape but generally they are about 17mm long, 10mm wide and 7mm deep. Smalti can be used whole but if you want to cut them we recommend either double wheeled glass mosaic cutters or a hammer and hardie; both of these cut cleanly and accurately and keep waste to a minimum - very important given the cost of the material. Choose your adhesive carefully as these smalti are transparent.
