We were visiting the Chihuly museum in Seattle when I saw an Airstream trailer set up outdoors to house the furnaces for their glass-forming demonstrations.
Looking inside the trailer, I was impressed by the "new"
furnace setting; 2,145 degrees fahrenheit!
Thinking about it, I guess you couldn't do this with molded
fiberglass. So, while we might win the hailstorm test, advantage Airstream for allowing you turn up the heat well past "cozy"!
