Forming. Is the process by which the raw materials selected for the porcelain tile manufacturing are moulded. It happens through dry pressing, which is a moulding used in making thin flat pieces with a regular geometry. During the pressing of tiles, several moulds can be used to provide the tile with a specific texture.

Clay minerals are an important group of minerals because they are among the most common products of chemical weathering, and thus are the main constituents of the fine-grained sedimentary rocks called mudrocks (including mudstones, claystones, and shales). In fact clay minerals make up about 40% of the minerals in sedimentary rocks.
