Porcelain Stoneware Tiles – the short story
A fit for purpose stone, made by crushing & combining natural rocks, sands, minerals, oxides and feldspar, then mechanically re-creating thousands of years of mother earth’s natural forces, by man’s pressing and kiln firing technologies.
Porcelain is a ceramic material created by heating raw matter, such as clays, sands, silicates and feldspar in a kiln to temperatures between 1,200 and 1,400°C. Properties associated with porcelain include considerable strength & hardness, a high resistance to chemical attack & thermal shock and a water absorption rate of less the 0.5% percent. These properties arise mainly from the formation of glass and the mineral mullite (a form of aluminium silicate) within the fired body at these high temperatures.
Stoneware is a category of clay, derived from natural rock (igneous, sedimentary and metamorphic) and is distinguished primarily by its firing and maturation temperature. In essence, it is man-made stone. Stoneware is recognised as being dense, impermeable and hard enough to resist scratching by steel point.
Tiles are a manufactured piece of hard-wearing material such as ceramic, stone, metal or glass. The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, meaning a tile composed of baked clay.
