Baking a bowling ball will be a good idea if you are going to do it from the Pro-shops. If you want to bake it at home, then we will suggest you maintain the heating temperature. The heat may bake the resin from the cover of the ball along with the oil. We recommend you not to use immediately after baking because too hot or too cold may crack the surface from the ball. After baking, let it cool down to room temperature. The cracked surface may alter the ball action.
