Various objects are obtained from ceramic processing, which concern an equally considerable number of sectors. By viewing the Ceramics Wikipedia page we can find all the variations and uses obtained through the manipulation and firing of clay. We focus on the processing of terracotta to better indicate the uses of the semi-finished products present on the site www.artecottosrl.com, they are ceramics which, after the firing process, present a color that varies from white to red, in relation to the presence of salts or oxides of iron. Cooking takes place at 980-1050 °C. The presence of iron oxide, in addition to giving the typical colour, also improves the mechanical resistance of the fired ceramic, contributing to the vitrification and reduction of the porosity of the article. Thanks to its stability, resistance to aging and lightness due to its porosity, terracotta is one of the most suitable supports for the artistic and artisanal creation of decorative subjects. Terracotta is generally distinguished from brick by a "more accurate purification of the clay". They are used both without surface coating and with coating. The former as structural and ornamental ceramics: vases, jugs, etc. The latter also serve as kitchen utensils: cups, plates, lamps, furnishing objects and decoupage supports.
