It's chemically inert, enabling direct contact with sheet metals of various alloying compositions at in-process temperatures approaching 900°C. This is certainly supported by high-temperature stability and thermal conductivity.
Yet another downside of the recipe is that, whether it is used in salt or soda firings, it'll most certainly make a glaze to the shelf. It is because silica, as noted higher than, is often a glass-former.
