The ldw test has more information on measuring the density of a dry ceramic.
Each sample fired to a higher temperature becomes more vitrified.
The volume of the cylinder is specified in the expression of results.
It is possible to access the bulk density of a porous ceramic sample by the archimedes method either by immersing a coated sample in a wetting liquid.
In ceramic engineering the most common method for producing ceramic components is to form a green body comprising a mixture of the ceramic material and various organic or inorganic additives and then to fire it in a kiln to produce a strong vitrified object.
Note that the samples are at or very near full density at the two lowest firing temperatures.
