A casting body should contain approximately 50 % clay material and 50 % nonplastic materials. Very fine clay particles will reduce the casting rate by blocking the flow of water from the slip into the plaster mould. Plastic clays should be substituted for less plastic ones and the clay part should be made up from more than one type of clay.

Ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride, or carbide material. Some elements, such as carbon or silicon, may be considered ceramics.Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.

Clay-brine process employing activated clay, NaCl, HCl, and HF as raw materials is the primarily advanced technology to synthesize cryolite in the present industrial grade. However, plenty of byproducts of fluorine-containing waste HCl at the concentration of about 10%~12% could not be utilized comprehensively and are even hazardous to the environment.
· The comparative study on preparation and characterization of modified bentonite and kaolin clay types is aimed at establishment of the ability of these clay types to adsorb pollutants. Its low cost, availability and recovery of clay give it added advantage of an effective adsorbent. The modified clay types were prepared by impregnation using various concentrations of either H2SO4 or NaOH in …

kaolin, ball clay, fire clay, bentonite, fuller''s earth, and common clay and shale. Kaolin, or china clay, is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminum silicate (Al2O3·2SiO2·2H2O), and other kaolin-group minerals. Kaolin has a wide variety of industrial
Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour ...

Clay storage and mixing should take place in a separate room. Bags of clay (and other pottery materials) should be stacked on palettes or grids off the floor for easier clean-up. All clay mixers should be equipped with local exhaust ventilation to remove fine silica dust particles from the air.
CLAY PREPARATION. The first step in working in ceramics is the finding of a plastic clay body. In the past, potters had to dig their own clay from locally available sources as there were no other options. Some potters still dig their own clay and feel a valuable connection to the earth through this process.
