The hardness test developed by Friedrich Mohs was the first known test to assess resistance of a material to scratching. It is a very simple but inexact comparative test. Perhaps its simplicity has enabled it to become the most widely used hardness test. Since the Mohs Scale was developed in 1812, many different hardness tests have been invented.

French flint pebbles: grind more with less. Superior performance as a grinding media compared to any other natural pebble, because of higher hardness, and higher resistance to abrasion Low pebbles consumption: 4.5kg of our pebbles are needed to grind 1000kg of white ceramic body (compared to between 7kg-20kg with other pebbles)

This process allows the production of stable and well-sized ceramic pebbles, which at the same time also guarantees the sphericity and surface smoothness, the theoretical density and the other properties, such as the resistance, the hardness and fracture toughness, etc., which are traditionally desirable.

In this paper, two kinds of ceramic pebbles, Li 4 SiO 4 pure phase ceramic pebbles and Li 4 SiO 4-xLi 2 TiO 3 multiphase ceramic pebbles were prepared by a melt spraying method at a superheating temperature of 100 ℃ and then tested for their performance. The proportion of pebbles with a particle diameter of 0.8∼1.2 mm reached the maximum of 24.02 % when the spraying pressure is 0.04 MPa

A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology.Pebbles are generally considered larger than granules (2–4 mm (0.079–0.157 in) in diameter) and smaller than cobbles (64–256 mm (2.5–10.1 in) in diameter).

If you still see no mark left on the pebble, use your steel nail to scratch it (hardness 7.5). If not even this leaves any scratch then you know that your pebble-rock is harder than 7.5 on the Mohs Scale. So, to identify your stone go to your Mineral Key and look for minerals that are of a hardness from 8+.

There are three types of density in rocks: dry density, wet density, and grain density. The data table lists the dry, wet, and grain densities of the samples. Additional wet densities for Wisconsin rocks can be found in “ Density and Magnetic Susceptibility of Wisconsin Rock ,” by S.I. Dutch, R.C. Boyle, S.K. Jones-Hoffbeck, and S.M. Vandenbush ( Geoscience Wisconsin , Vol. 15, p. 53–70).

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn''t as complex as you may think because water''s density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
