In some blacksmith gas forges the insulation materials are a castible refractory. This can be similar to a concrete which you mix up and fit around your gas forge chamber. This is more of a heat shield than a genuine insulator. This type of gas forge will require a little while to heat up. The refractory acts as a heat sink until it has soaked up enough heat which it reaches an equilibrium between the high temperature inside and the loss towards the environment.

The refractory is more durable compared to the common fiber insulation, nevertheless, you sacrifice thermal efficiency. It’s also much heavier compared to Kaowool insulation.
