DIY Hand Painted Wine Glasses. Preheat oven to 350 degrees with the glasses inside, then bake them at 350 degrees for 30 minutes. After 30 minutes, turn the oven off and leave them inside until completely cool. The paint should then be baked on and top rack dishwasher safe, but I would still recommend hand washing.
