Stone Parana Extra Grey (porcelaine stoneware)

Description

Slabs have a grey background colour with a few dark grey veins.

WE BUILD
in the factory state-of-the-art products, using construction processes covered by international patents.stonesi.e. blends of clays, sands and minerals that nature compacts through tectonic motion and fires through the heat of the superficial layers of the crust.natural because we employ the same forces used by nature itself (pressure and fire), following construction processes which reproduce its features and characteristics. ecocompatible because sands, clays and other minerals are quarried without damaging the environment, using sensitive, strictly enforced procedures and know-hows.with very high performancebecause clays, sands and materials used are extremely pure; the compacting pressure is very high (480 kg/cm2); the firing heat is much higher than the one of a volcano (1300 °C and more, compared to 1100 °C).
