What are the basic materials that make up the porcelain?.
As already mentioned in the introduction to this study, it can not talk about the porcelain without knowing the soil and their properties, which are the basic material for most types of ceramics, soils mixed with water form the mud flexible and sticky stainless formation and contraction and cohesion after drought and stainless rigidity and ossification after firing, and the soil is a mixture of silica and Almanaiziom Clay called in Arabic is called Argela (Argilla) in Latin.
The process of preparation of clay or dough clay-based ceramics because the choice of materials and methods of preparation determine the pattern pieces made from them for this, the soil passed through several stages before its formation liquidated first to be cleaned of impurities and so crushed and Tngelha and Whatsoever, and transferred later to the basin settling, may remain slurry in the basin for a long time depending on the need for basic manufacturing, and after drying mud taken from the basin and add the fine sand then knead with hands or legs in order to rid of the bubbles air, and becomes more homogeneous and fit for work.
