Bianco Verona White Marble Dust (1 kg)

Product Details:

1 kg bag (2.2 lb)

Verona White marble ground to medium coarse powder. Use this marble dust to make grounds, for adding textural and handling qualities to paints, and as filler in lime plastic for the intonaco layer of fresco.

Imported from the world-class deposit in Italy, it is ground to a granular particle size of 0 to 0.7 mm to retain its crystalline shape.

Marble is calcite formed from limestone with heat and pressure over years in the earth's crust. The pressure causes the limestone to change the particle structure, causing it to recrystallize. Fossilized materials in the limestone, along with its original carbonate minerals, recrystallize to form large, coarse grains of calcite.
