Many people seem happy with a forge made from two, hollowed out firebricks as a small, portable solution. However, the soft firebricks do seem to take a beating, crack and fall apart fairly easily. Some people will wire them together, but has anyone had any luck with putting them in a casing of some kind? It would seem as if this would extend the life of the forge and also make it less fragile when toting it around if they were in some sort of shell.
