Siena also released single-fired tile with Stoneware, 20-by-20-centimeter frost-resistant, non-slip tiles in Mediterranean colors.
Exhibit booths at Cersaie also incorporated the more traditional mosaic, terracotta and clinker tiles (a natural clay product, typically extruded, with properties similar to red stoneware) into their product offerings. Ferrone followed this trend with the introduction of Maiolicato, a collection of clay terracotta tiles. Sire offered vitrified clinker tile in the Evolution Series. The company manufactured these non-slip, frost- and scratch-resistant tiles from a mixture of clays cooked for as long as 36 hours.
