Porcelain is a ceramic material made by heating selected and refined materials often including clay in the form of kaolinite to high temperatures.
These tests were all made from the same terra cotta body and fired to increasingly higher temperatures.
C729 11 2016 standard test method for density of glass by the sink float comparator.
Or by immersing the uncoated sample in a non.
However at 2057 f 1125 c a very slight bloat is evident.
Thus the density of a powdered mineral is actually referring to the average specific gravity of the tiny particles making up that powder.

We have collected a number of charts detailing applications and properties for some of the most commonly used ceramic materials.
Density measurements of ceramics and advanced materials is amongst many other tests that can be performed on stable micro systems physical testing instruments.
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.
A third kind of density is the apparent density of a dried or fired ceramic body which of course often contains many air pockets.
Helium under precisely known pressure is used to fill small voids within a specimen.
Note that the samples are at or very near full density at the two lowest firing temperatures.
Each sample fired to a higher temperature becomes more vitrified.
