The material which goes into making seashell chinaware is completely natural, sustainable and environmentally-friendly; gathered from beaches where mother-nature deposits and replenishes it with every incoming and outgoing tide.
Porshelina is completely food-safe; in fact seashell naturally contains a higher level of calcium which helps kill bacteria; making it more hygienic. It is both microwave and dishwasher safe. Porshelina provides strong, natural, elegant chinaware which is both ethical and sustainable.
The history of china can be traced back thousands of years. The chinese developed ceramics, which is the process of heating clay in a kiln to temperature of between 1,200 °C and 1,400 °C to develop a product which is permanently hardened. The process became more sophisticated leading to the development of porcelain. Porcelain was a superior product as its surface was both smoother and lighter. Before the 18th century this porcelain was exported to Europe in vast amounts as Europeans at that time did not have the technical expertise to produce porcelain. The term "China" has become so identified with the product it is still in widespread use.
Porcelain generally is produced by heating kaolin or china clay in a kiln. This produces a strength and toughness coupled with it a whiteness and translucency which make such a desirable product. Porcelain may be referred to as china or fine china. The term Porcelain is from the old Italian word porcellana ( cowrie shell ) which was used because of the similarities with the shell of its translucence.
In 1748 Thomas Frye developed what is now known as bone china by adding cattle bone to create what he defined as fine porcelain. Josiah Spode developed this further circa 1790 with his formula six parts bone ash, four parts china stone and three and half parts china clay. Today the formula for bone china is about fifty per cent bone ash, twenty five per cent kaolin and twenty five per cent Cornish stone.
The latest development in china is now available. The next wave of chinaware arrives on our shores. Porshelina has been developed using seashells and the latest manufacturing technologies to create a new product which offers a lighter, more durable and translucent chinaware without the need for bone content.
