This is actually something I made in art my junior year of high school. Turn an old record into an awesome bowl. First spray paint one side white, paint a design with acrylic paint (mine is my finger print, which was the assignment), then melt it in the oven and cool it over a bowl.
I did this as a kid at school as a gift for my Mom. We melted records, then we mod-podged squares of Christmas wrapping paper to them to make them little Chirstmas candy bowls. Now, I think it would be a terrible waste of an antique. I would never melt my vinyl!
