Hemimorphite Molecular Model

Zn4(Si2O7)(OH) 2· H2O, a component of calamine. It is a sorosilicate mineral which has been historically mined from the upper parts of zinc and lead ores, chiefly associated with smithsonite, ZnCO3.

Hemimorphite most frequently occurs as the product of the oxidation of the upper parts of sphalerite bearing ore bodies, accompanied by other secondary minerals which form the so-called iron cap or gossan. Hemimorphite is an important ore of zinc and contains up to 54.2% of the metal, together with silicon, oxygen and hydrogen. The crystals are blunt at one end and sharp at the other.

This model is hand made and is a permanent structure. We use only grade A materials including 1 inch balls made of hard maple wood which includes an enamel painted finish. Polished steel rods are used to connect the wooden balls together.

Hemimorphite  includes 120 1 inch balls.
