Most methods of fixing warped record
s of the vinyl
variety involve obtaining two
12" squares of glass
. Place the record in between them and either leave the package thus in the sun
or place it inside a 200°F oven.
These methods both sound risky, and since I've tried neither for any of my warped records (quite a few of which I'd rather keep warped than not at all), I can't recommend these.
How to prevent records from warping is a whole other story.
Some people warp their records on purpose to create bowls or flower pots. They would consider further warping of a damaged record to fix the problem. Don't try to eat out of such a device. There's still that inconvenient hole at the bottom, and all your broth, sauce, or milk will leak out.
