This method has been designed to eliminate the inherent guess work built into ASTM C128 and AASHTO T-84— the current cone and tamper methods in use today. Remember, density doesn't equal firmness, so keep this in mind when selecting a mattress. To keep things easier, densities are often expressed as "specific gravity", which just means they are expressed as a ratio of the gravity of water. As it is a ratio, specific gravity is unitless. Dark colored, paint-on glazes used for detail work need to have a high specific gravity so they can cover well with a single brush stroke (e.
