Are porcelain dishes safe in the oven?

Here's why:

* "Porcelain" is a broad term: It can refer to different types of dishes, some oven-safe and some not.

* Check for markings: Look for the "oven safe" symbol (usually a picture of an oven) on the bottom of the dish.

* Manufacturer instructions: Always refer to the manufacturer's instructions for specific temperature limits and usage guidelines.

* Glaze: The glaze on the dish is crucial. Some glazes are designed for high heat, while others are not.

Here are some general guidelines:

* Bone china: Often not oven safe, even if marked as dishwasher-safe.

* Fine porcelain: May be oven-safe, but check for markings or manufacturer instructions.

* Heavy-duty porcelain: More likely to be oven-safe, but again, check for markings.

If you are unsure, it's best to err on the side of caution and not use the dish in the oven. You can also use an oven-safe alternative, like a Pyrex dish, for cooking.
