A few minerals such as calcite and kyanite have a hardness that depends significantly on direction. [9]: 254–255 Hardness can also be measured on an absolute scale using a sclerometer; compared to the absolute scale, the Mohs scale is nonlinear. [8]: 52 Tenacity refers to the way a mineral behaves, when it is broken, crushed, bent or torn.

These minerals are found in high-grade metamorphic banded iron formation and form a compositional series between Mn 2 Mg 5 Si 8 O 22 (OH) 2 (tirodite) and Mn 2 Fe 5 Si 8 O 22 (OH) 2 (dannemorite). Calcium, sodium and potassium concentrations in cummingtonite are low. Cummingtonite tends toward more calcium substitution than related anthophyllite.
Mineral tests are simple physical and chemical methods of testing samples, which can help to identify the mineral type. [1] This approach is used widely in mineralogy , ore geology and general geological mapping.

Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns [7] or in contact with metamorphic rocks.
