The kinetics of the dissolution of silicates, aluminosilicates and quartz is described by a novel theory of dissolution. The experimental data for the rate of dissolution of these minerals shows a remarkable pattern: for many of these minerals, the order of reaction with respect to H + is close to in the acidic region, and the order of reaction with respect to OH − is close to in the ...
Iron Quartz Adaptogenic Stones. The Crystal "Adaptogen" which is essential for Recharging and Grounding is Iron Rose Quartz. Other names for this stone include Hematoid Rose Quartz or Sacred Heart Rose Quartz. This is a very special stone from Madagascar, with a natural alchemical combination of Iron (Hematite) within a matrix of Rose Quartz.

Main Body. Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (, S2–)) or an anion complex (, SO42–). For example, in the mineral hematite (Fe2O3), the cation is Fe3+ (iron) and the anion is O2– (oxygen).

Purity of Quartz Crystals Unlike most minerals, a clear quartz crystal is always chemically pure, with a SiO 2content approaching %, often more. There are basically two reasons for this. First, quartz has a macromolecular structure. It does not contain isolated ions of some element that could easily be replaced by another element.
