Sustainable ceramics derived from solid wastes: a review
In all these ceramic products are mostly manufactured by the consuming of the massive amount of raw materials from nature. The oldest and most used raw material of ceramic is natural clay. Generally, the pottery is made by the conjunction of raw materials like clay, silica, and a certain amount of alkali-bearing materials (feldspar) as fluxes.Web
