First, I preheated my oven to 200 degrees. Place a mixing bowl upside down onto a baking sheet (this makes it easier to put in and out of the oven. Set your record on top of the bowl. Stick it in to "bake" for 8 minutes. The record will get hot and start to deform around your bowl.
When you take it out of your oven, it should look something like this. Let it cool completely before you take it off the bowl base. After it cools, it is just as strong and sturdy as it was before.
This was so easy to do, and the results are wonderful!
