What? Did you draw on bowl with permanent markers? Not dishwasher safe or even dish water safe. The only thing that stays on glass is the paint you bake on and that can't go in dishwasher but you can hand wash.
Hi Darlene, according to this article even if you use OIL-BASED PERMANENT Sharpies to decorate mugs and bowls, they are NOT dishwasher safe. :(
I agree with Kelli and Janice. Anything made with markers should be gently hand washed. Wishing you the best.
