Rare vintage "super duty" fire brick - Walsh Refractories Corp - Mullitex- MO
Artifact.The brick has some chips and mortar residue. I haven't done anything
to them other than hose them off. I'm not an expert on this, so if you need
information that the photos don't show, I'm happy to answer questions. Please
refer to the images for more details and the items condition.
