[Stoves] the 150 gasifier in operation in Vietnam (Matt Redmond)

Ron, List,

Interesting find. You reported that the silicon carbide meshes for drywall
sanding are really just paper meshes coated with silicon carbide.

I was trying to think of other materials that can handle high temperatures
and ceramics came to mind. Ceramics are often used in metal casting
processes. Aluminum Oxide, or even some sorts of fiberglass have high
working temperatures.  Ceramics generally have higher emissivity than
metals (~ 0.7 I think).

It looks like fiberglass meshes are often used to filter molten aluminum
and iron for casting operations.  Perhaps something like this would have
longer lifetimes? Again, cost may become a big issue, but here are 2 that I
found:

Just throwing a few more ideas out there.
