Porous Aluminum eh? Wonder how well it stands up to gallium, or acetylene, or MAP gas, or a grind wheel instead of a cutoff wheel.

the ceramic inside is alumina, so same material as both a cutoff wheel and a grinding wheel. They mention that it's not the best purity and hardness, but it's pretty good.
