Abstract
A flotation method is described that enables the density and porosity of small specimens to be measured accurately by comparing their densities with those of reference specimens. The method uses the subtle, but accurately known, variation of the density of water with temperature to bring about neutral buoyancy of a specimen-float composite. Measurements can be made easily and quickly and the expressions derived for density and porosity are readily evaluated numerically.
