GLAZING is the process whereby a liquid mixture called GLAZE is applied to the surface of the body material so as to create the final appearance of the tile.

Currently, the most widely used glaze is based on lead, a substance that is extremely harmful for both the environment and man's health.

The lead-free glazes now available on the market are only used to a small extent as they are somewhat difficult to apply (higher temperatures are required to achieve the same viscosity) and are not so attractive as to appearance (less glossy, tendency to turn grey, presence of residual porosity).

Thus the aim of the project is to create lead-free ceramic glazes by using boron instead; glazes with the same quality and characteristics as the lead-based ones and able to achieve an extremely attractive tile finish. This by creating a demo pilot system so as to consolidate the technique.
