Some storage heaters have metal 'boxes' full of granular ceramic material such as bonded magnetite. Yours may be this type.
Mine aren't boxes of anything, they are clearly cast 'bricks' of some sort of metal that are fairly irregular on the outside to provide channels for the air that is used to get the heat out of the pile of 'bricks'
There is no way that can ever fail catastrophically, the worst that could happen is one cracks and that crack would be completely harmless.
There are fusible links that handle a failed thermostat so it doesn't heat forever. The heating elements and fusible links are easy to change if they do fail and I have changed a couple in the 40 years I have had it.
