Synonyms: Pietra Maremma, Arenaria Grigio Perla Toscano
Location: Grigio Perla Toscano sandstone is quarried near Manciano, Provincia di Grosseto, Tuscany, Italy.
Description: Grigio Perla Toscano sandstone is a light beige/grey medium to coarse grained, litharenite sandstone with yellowish veins and reddish patches in places. This stone internationally may be nominated as a sandstone and in the area of application of the European Standard this stone must be nominated as sandstone.
A small sample of Grigio Perla Toscano sandstone is reasonably representative owing to the natural variation in colour and veining. Swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use and polishing may be possible.
Mineral Composition: Average by %:
Sandstone: Is an arenaceous sedimentary rock composed mainly of feldspar and quartz and varies in colour (in a similar way to sand), through grey, yellow, red, and white. Sandstones are often relatively soft and easy to work which therefore make them a common building and paving material. Sedimentary rock is formed from the weathered remains of other rocks. Sedimentary rocks are formed from overburden pressure as particles of sediment are deposited out of air, ice, or water flows carrying the particles in suspension. As sediment deposition builds up, the overburden (or lithostatic) pressure squeezes the sediment into layered solids in a process known as lithification ("rock formation") and the original connate fluids are expelled.
