Hardness (Moh) - HMOH

This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com. Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.

Notes

Hardness is measured on the Moh's hardness scale as follows:

10 Diamond
9 Corundum
8 Topaz
7 Quartz
6 Feldspar
5 Apatite
4 Fluorspar
3 Calcite
2 Gypsum
1 Talc

If a specimen to be tested can be scratched by a mineral from the list, it is softer than that mineral. If it in turn will scratch another known mineral, it is harder than that mineral.

Variables

VAL - Value (V)
