Ceramic or fired brick was used as early as 3000 bc in early indus valley cities like kalibangan.
Ceramic used for bricks.
These bricks were made of red clay fired on all sides to above 600 c and used as flooring for houses.
The bricks typically line the inside of a kiln furnace fireplace etc and serve as great insulators making heat loss minimal and energy use.
Of course these brick types are not set in stone even if the bricks themselves are.
It is a useful and necessary term because especially when initially found in archaeological excavation it may be difficult to distinguish for example.
These are samples of common materials used to create bricks and researchers often experiment with modifying levels of clay sand lime fly ash cement and other materials in any given brick to find combinations with optimal properties.
Kiln bricks also referred to as fire bricks or refractory bricks are made from ceramic refractory material that can withstand extremely high temperatures such as those achieved in kiln firings.
Building bricks for extreme weather.
People first started making ceramics thousands of years ago pottery glass and brick are among the oldest human invented materials and we re still designing brand new ceramic materials today things like catalytic converters for today s cars and high temperature superconductors for tomorrow s computers.
