Souvenirs to Riga: Airfreight of Porcelain from Colombo to Riga
Kaolin ("high heel" from Chinese) was found in China around 620, and for hundred years since that was used as the base for the finest ceramics – porcelain.
China kept manufacturing technology secret for centuries. Yet, just 500 years later, Koreans established production of so-called hard porcelain: the items made of white clay and spat with insertions of sand or quartz exposed to hard firing. Attempts of the European to steal the hard porcelain formula had no success until Johann Friederich Bottger invented own porcelain production method. Such porcelain differs with its strength, high resistance towards head and acids, tightness, transparency, shell-like structure, and pure bell sound.
Soft porcelain also known as decorative porcelain mostly consists of vitrification mixtures, so-called fritt, contains sand or flit, saltpeter, sea salt, bi-carbonate soda, alumen, and ground alabaster. Once specific melting time lapsed, malm containing gypsum and clay is added to the mixture. Compared to hard porcelain soft porcelain is more transparent, its white color has softer sometimes nearly creamy shade, yet it is less heat resistant. Chinese porcelain from the modern point of view is soft porcelain as it contains less Kaolin compared to hard European porcelain, and it is also fired at lower temperatures, and is less strong.
Bone china is a kind of "compromise" between hard and soft porcelains. It was invented in England in attempts to recover natural Chinese porcelain formula in about 1750. In addition to kaolin and felt, it contains lime phosphate and over burned bone making its melting easier. Boneporcelainisburnedat 1,100-1,500C. Real porcelain lovers prefer it over the others due its resistance properties, delicacy and whiteness.
