0.1 - 0.6 mm, fire-dried Basalt Black, medium fine sand belongs to the group of magnetic pigments. Basalt is an eruptive rock of volcanic origin. When the basalt magma cools, basal t deposits are formed. In Germany, it is usually found in the form of hexagonal prisms on both sides of the Rhine in mid-elevation mountains. Basalt is very hard and resistant to water and weathering. No crystallization structures are visible. We offer basalt as a filler material for gray mortar mixes in various forms of milling and fire-drying. Show more
