Hi David: A graphite fiberglass coated fixture will not deform. Graphite will provide the backbone and the glass will keep it from wearing due to handling and seal the graphite. Maybe this has not been done yet, but graphite melting point is 4100 deg C, so it does not bend at 300 deg C at all. If you propose to a fixture manufacturer if they could build a special fixture for you, they might do it.
