THE DIFFERENCE BETWEEN REGULAR BRICKS AND FIRE BRICKS
The most important difference is that fire brick can withstand extremely high temperatures and regular bricks cannot. Some other differences are that fire bricks are heavier than regular bricks and they are denser. Firebricks are usually white but there are various different methods you can use to change their colour. Fire bricks can be tinted, stained, or dyed during manufacturing in order to change their colour. Since it is so easy to change their colour, this makes them more customizable than regular bricks.
Regular bricks have much more thermal conductivity than fire bricks. Thermal conductivity happens when temperatures travel from one brick to another, which creates insulation. This is why fire bricks are used for items and furnaces, to help retain the heat.
