Porcelain stoneware is a high performing, non-equilibrium, and
glass-bonded material manufactured through a fast firing cycle
with peak temperatures of about 1200–1300 C [1–3]. Its peculiar
technological characteristics, such as high density (Water Absorption
WA < 0.5% ISO13006, WA < 0.2% in current production [4]),
frost and chemical resistance, surface hardness, and resistance to
abrasion led to an outstanding increase in production and sales
of porcelain stoneware tiles
