2. Devices for constructing such paraboloids are known as rotating furnaces.
3. After reverberatory and rotating furnaces the recovery boiler was on its way.
4. The same technique is used to make solid paraboloids, in rotating furnaces.
5. The assembly ( or rotating furnace ) is then heated while spun at slow speed until the glass is liquid, then gradually cooled over a period of months.

8. Steward's Mirror Laboratory ( SOML ), located under the east side of Arizona Stadium, has pioneered new techniques of large mirror production, including spin-casting lightweight honeycomb mirrors in a rotating furnace, and stressed-lap polishing.
