This range of smalti is manufactured in Italy by the family firm of Dona from Spilimbergo and containsalmost 100 colours. It is sold in 100gram bags which is approximately 35 pieces. This will cover an area of 8cm x 8cm. The pieces are hand-cut and therefore quite variable in shape but generally they are about 17mm long, 10mm wide and 6mm deep. We recommend cutting these tesserae with Leponitt wheeled glass cutters as we have found that they are easy to use, cut accurately and produce minimal waste which is key given the cost of the tiles !
