Calcite, line and marble | Earth Sciences Museum | University .

Calcite is number 3 on the Mohs hardness scale; it can be scratched readily by a knife blade or geologic pick. It has a specific gravity of 2.71. . Scientists test natural rock to see if it is line by pouring cold diluted hydrochloric or sulphuric acid (10% solution or vinegar) on it. Line gives off bubbles of carbon dioxide.

The Strength and Hardness Ratings of Granite and Marble

Selecting the right counter top stone for your home depends on numerous factors, including your budget and design choices. Another important factor is stone strength. Each natural stone has a strength rating often referred to as its Mohs hardness. The Mohs scale of mineral hardness was developed to identify the strength.
