Keith Henson I had assumed that if there were a problem in this area it would be transporting the furnace. If the material to be melted were placed in a cylinder of, say, ceramic, heating the cylinder would cause the outgassing to come from the ends with some reasonable velocity. If the mirror were on the side of the cylinder it would be at right angles to the outgassing as should get minimal depositing. This is so simple and obvious that I must be missing something.
