Dry-based glazes - Spanish sector EPD

The glaze is typically prepared in the form of an aqueous suspension that is applied onto the support (the part of the tile made of clay material). Subsequently, it is subjected to a firing process that results in the ceramic tile with the desired final properties.

Glaze formulations typically include a mixture of frits, inorganic pigments, raw materials, semi-finished products, and additives. This mixture is applied as a thin layer onto the ceramic support. Upon firing, it melts and upon cooling forms a compact mass with a predominantly vitreous structure, insoluble in water, physically resistant, and resistant to the chemical agents it will encounter during its use. Additionally, it adds aesthetic and decorative elements to the support on which it is applied.

Just like frits, glazes have a wide variety of uses and applications. Ceramic uses/applications predominate, but they also provide added value in sectors such as construction, automotive, glass decoration and metal surfaces.

The dry-based glazes are the result of the dosing mainly of frits, pigments, raw materials, semi-finished products and additives. The dosing of the different elements that constitute glazes will be determined by the final properties expected after their subsequent application and firing. These can be delivered to customers in solid form in big bags for on-site milling or sent to other processes for wet milling or micronizing.
