Why is refractory mortar needed for iron stoves?

In iron cookers, the roof of the oven section needs to be covered with clay mortar to provide more even heat in the oven and to prevent the heat from rising and falling too quickly when firing. The mortar is also necessary to prevent the stove from cracking if the fire is too hot. In old iron stoves, you can usually only see the remains of this insulation in the form of a layer of gravel on top of the stove. Refractory clay mortar should only be laid on top of the stove roof.
