Harmful Ingredients of Brick Lime. Excess lime melts the bricks and disfigures it. If CaCO 3 exists (in the purest form, i.e., if it contains at least 95% CaO) in lime-lump in brick clay, it converts into quicklime on burning. When these bricks come in contact with water, quicklime slakes and expands.

Ball Clay (or plastic clays), is a kaolinitic mineral clay and a member of the phyllosilicate group of minerals. It occurs generally as an aluminium silicate comprising weathered forms of quartz, mica and kaolinite. Although similar in chemical composition, BALL CLAY is not as common as kaolin and differs substantially in physical characteristics.

Clay materials are composed of solid, liquid and vapour phases. The solid phases are of mineral and organic phases that make up the framework of the clay materials. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called 'amorphous' inorganic phases. By definition, minerals are crystalline solids with well-ordered crystal ...
