the matt or glossy glazing, with metallic or shaded effects, is a terracotta treatment that combines the texture of the element with the profound application (during kilning) of a colored, naturally waterproof, washable layer. The glazing can therefore be applied on the natural smooth element; on the sandblasted one; and on the rustic or orange peel element, with a combination of high effects. The textures of the element, the colors and the finish (glossy or opaque) of the element are highly variable parameters and the mix-design is precisely what makes the final effect unique and unrepeatable: craftsmanship and originality is inserted in a standardized production process.
