Best Answer:i've only put cold in mine as they are rather delicate. i am a caterer and bought six. i love them for dressings and other sauces but i've already broken 2 at the handle. i wouldn't recommend dishwashing it if you use particularly hot water (which i do) but the other 4 seem to be holding up well with a careful hand washing. for the price, you really can't go wrong. they are adorable and the perfect size.
