These light fire bricks 1430 °C/2606 °F have the best insulating effect of all the bricks offered here, but they are relatively soft and porous. Therefore, I recommend using them only where they are not exposed to mechanical stress and the classification temperature is not exceeded. E.g. as a combustion chamber for gas fires that are not regularly used for fire welding at high temperatures or as under-insulation of the light fire bricks 1800 °C in the construction of steel melting furnaces. For gas fires, which are often used for fire welding, and for the doors of gas fires, I recommend the light fire bricks 1650 °C/3002 °F.  

Light fire bricks are suitable for a variety of applications. Unlike normal firebricks, they only absorb little energy (heat) but radiate it again. This significantly increases the efficiency of gas fires or melting furnaces, gas consumption decreases and the achievable temperature increases. The warm-up time is also drastically reduced.

I used to build gas fires with a core of high temperature ceramic fiber mat and a coating of blast furnace concrete. However, this combination has several disadvantages. Even the best ceramic fiber mat will shrink over time, creating voids under the concrete lining. The thin and often awkwardly shaped concrete coating has a strong tendency to crack after a while. As a result, in my experience, gas fires built in this way are not very durable and have to be repaired more frequently. That's why I now only use light fire bricks for the construction of gas fires and smelting furnaces.

The light fire bricks 1430 °C/2606 °F and 1650 °C/3002 °F can easily be brought into the desired shape with a saw, a rasp or sand paper. Light fire bricks 1800 °C/3272 °F can be easily processed with an angle grinder with a diamond disc.

With the right mortar, dimensionally stable and form-fitting components can be produced, e.g. combustion chambers of gas fires.
