Ceramic clay is fired to over 2000 Degrees and Pure clay is fired only up to 2000 Degrees, Why?
Ceramic clay is a composition of different chemicals, chemically extracted inorganic minerals and metallic and nonmetallic elements so it needs to be fired to higher temperatures to fuse together all these separate foreign elements.
Pure-clay is one single entity just as it is found in nature. All the nutrients in the clay are already bound together into one. The firing in this case is done only to completely eliminate chemically bound water (H2O). Since it’s already one body the clay gets vitrified quickly at a much lower temperature — another reason why Pure-clay is a far more eco-friendly option!
