200 degrees is TOO HIGH!!!
The recommended temp tossed around is 125 degrees F.
The way to get this low a temp is with lightbulbs stuck over and under the LP in the oven.
Need a temp guage, (a fine one is to get those computer ones LCD remote probe, battery operated.
Finding good glass is tough.
And heat and cool gradually.
Another person uses the car. Put the item sandwich in the car on a warm sunny day. leave until evening and it is cooled off. works too. The big thing is the thick glass, 1/4 to 3/8 inches.
