I decided to go ahead and make some centerpieces for the tables at the reception. If you haven't signed up, you might like to join your local Freecycle. That's where I got the supplies for my latest project. I asked for record albums in any condition, and a nice lady was kind enough to donate about 75 of them to our cause. I got online and searched for directions on how to make record album bowls, because I'd seen them and really liked them.
First, make sure you don't have some great album you'd like to keep (even though you probably don't own a record player).
I cleaned the records first, per Jerry's suggestion, as it has to be easier to clean them before they are hot and the dust sticks to them. All I used was a damp paper towel.
Once the oven is heated to 350 degrees, place the album on top of a coffee mug that's resting on a cookie sheet.
Keep an eye on it! The directions I found online said to leave it in for 5 minutes, but it didn't take nearly that much time. After about 15 seconds I could see the record start to wilt. I would open the oven, turn the pan and let it continue to wilt. Once it has drooped sufficiently on all sides, remove it from the oven with potholders.
The album cools rather quickly, so start moving it to the shape you'd like. I kept the potholders on my hands for a bit so I didn't burn myself. After a while you can use your bare hands, just be careful. Once you feel resistance, time is very limited so start shaping quickly.
Set it on the counter and let it cool. Put down paper towels if you're afraid of messing up the counter top, but I didn't encounter anything like that. I made a dozen in less than an hour. I plan on putting non-edibles in these bowls. If you decide to put food inside, put another bowl in it or line it with plastic wrap!
