Yes! It depends upon whether or not there are enamel coatings present or not on your pot or pan; otherwise oven should not come near them as enamel can crack or get damaged if they come into contact with heat source too much while using them outside of oven (in microwave). Always make sure that whatever type of enamel coated product (oven safe or not) that you are using it on an oven safe surface or bakeware with an enamel coating before placing them into oven! The same applies when baking as well (i don't know how it works exactly but we do know it does work!). To summarize if any coating (enamel) present in cookware then its ok! But if there is no coating then do not use those products! As far as I know we don't have any report from our customers who have used enamel coated products directly inside oven so far but I would not take chances if I were you!
