cutting tesserae

cutting – the method used to break up materials into various sizes of tesserae. The hammer and hardie have been used since ancient times and are still one of the preferred methods for smalti & stone. The smalti or stone is placed on the blade of the chisel at right angles and by delivering a sharp blow with the hammer a clean-cut is made. To facilitate cutting glass, the surface may be scored beforehand with a diamond tool. With smalti, since the cut edge reflects more of its brilliance, it is usually placed facing outwards in the mosaic (except in the case of metal-leaf tesserae). Modern tools for cutting include tile nippers, tile cutters, wet saws & glass cutters. m.a.s. mosaic glossary
