Is it safe to use dinnerware with crazing?

It depends on the type of dinnerware and the extent of the crazing. Some types of dinnerware, such as bone china, can withstand a limited amount of crazing without becoming unsafe. However, if the crazing is extensive, it can allow bacteria to grow in the cracks, which can make the dinnerware unsafe to use.

If you are not sure whether your dinnerware is safe to use, you can contact the manufacturer or a qualified health inspector.
