Density (Specific Gravity) - DENS

Notes

This is the density of the actual mineral solid, not the weight of the bulk material powder. This is obvious if this value is being quoted for a mineral but can be confusing if it is for a powder. Thus the density of a powdered mineral is actually referring to the average specific gravity of the tiny particles making up that powder.

A third kind of density is the apparent density of a dried or fired ceramic body (which of course often contains many air pockets). The LDW test has more information on measuring the density of a dry ceramic bar.

ASTM C-128

Variables

VAL - Value (V)

The specific gravity of the solid itself (not the powder).
