Sintered Stone Supplier: StoneX USA

Large-format porcelain is one type of sintered surface, and it is the one StoneX USA supplies: porcelain slabs in 2 cm, 1.2 cm, 9 mm and 5.6 mm thicknesses, fired from natural minerals at very high temperatures without resin, from our warehouse at 1735 S 106th St, West Allis, WI.

What is sintered stone?

Sintered stone is made from natural minerals compacted and fired under extreme heat and pressure without resins. The result is non-porous, UV-stable, scratch and heat resistant – suitable indoors and out.

Is sintered stone the same as porcelain?

They are closely related and often specified interchangeably. Both are vitrified, non-porous large-format slabs; sintered stone typically carries its mineral composition through the full body rather than only on the printed surface.
