These light fire bricks 1650 °C/3002 °F have a very good insulating effect and show good resistance to mechanical stress. They are stronger and heavier than the 1430 °C/2606 °F light fire bricks. That's why I recommend them for the doors and the combustion chamber of gas fires and for the construction of aluminium, bronze and copper melting furnaces.

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.
