Vacuum sealed compressed Fiberglass with ceramic coating. Insulation similar to what was used for the space shuttle heat shields. This was original designed for some advanced semiconductor processes but never used. Will make a good metal smelter. This is the insulation only. Three pieces: bottom, middle and top. The bottom is 12 inches in diameter, six inches thick with one small hole on n center. The middle is 12 inches in diameter with a six inch diameter hole in the center (3 inch thick walls). It is 12 inches thick. The top is 12 inches in diameter, 6 inches thick with three holes.
