Aqua-garco is a naturally occurring mineral with uniform physical, chemical, hardness and microstructure characteristics, which provide the essential properties for a wide variety of industrial uses.
Aqua-garco is the compositional variety known as almandite. There are no free elements; all oxides are combined chemically as an iron-rich aluminosilicate, which has the formula: Fe3Al2(SiO4)3. Texturally and compositionally uniform in all sizes. All material mined from the same high-grade deposit.
