Baked marbles: Bake the marbles on a cookie sheet at about 325 - 350 for 20 minutes, take them out of the oven and immediately place them in a metal bowl or sink of ice water & they'll crack on the inside. Great idea! 40 years ago, this was HOT stuff with kids and teens I used to do this with my grandma
