For best care:

Oil your pan with neutral-flavored vegetable oil or cooking spray before each use; a nice patina will develop over time. For additional prevention of sticking, sprinkle a thin layer of cornmeal or semolina into the bottom of the oiled pan.

Putting your room temperature pan into a preheated oven is fine.

Protect from extreme temperatures. Never put in freezer; don't transfer from refrigerator to hot oven, or vice versa. Let it cool before washing.

Hand wash with warm water only. Do not use soap as stoneware will absorb it.

Do not use under a broiler or on a stovetop.

No need to soak in water before use (it's neither recommended nor necessary).

Protect your kitchen table and counter from scratches. Set pan on a trivet when it's not in the oven.
