Brick earth used for manufacturing bricks tiles is more pure and is prepared more thoroughly than the one used for manufacturing bricks. Tiles, being thinner require careful burning. … Read more Tiles, Earthen Ware and Glazing

Evaluation of the material (Dimensions)

Dimensions

This gives the superficial evaluation of the material i.e. shape and size. Density The terms density is the mass per unit volume of material in its natural state. The properties of material such as strength, stress and other mechanical, thermal and electrical properties of material etc are greatly influenced by its density. Simply, It is … Read more Evaluation of the material (Dimensions)
