How the Mohs Hardness Scale Works. To rank a mineral's hardness, mineralogists scratch its surface with another mineral of known hardness. If it scratches the surface, it's harder; if not, it's softer. For the in-between cases, they work their way up the scale. The Mohs scale is a useful tool for quickly identifying minerals in the field.

*And terrestrial orchids growing in limestone-rich regions will likely require a higher pH (7-7.9). In nature a plant has evolved over millions of years to exist in the place it grows. If it's growing on a tree, the pH of rain water is low. If it's growing on limestone rocks at the base of a mountain in Borneo or the Amazon, the pH is high.
