Is the skillet really pre-seasoned?

Yes. It ships with a factory seasoning, so you can cook on it after a quick wash and dry. Expect the seasoning to improve with use, and add a thin coat of oil after washing.

Can the glass lid go in the oven?

The pan is oven safe, but the glass lid is best kept to stovetop and moderate oven temperatures. Do not use the lid under a broiler or over direct high heat.

Will it work on a smooth-top electric range?

Yes, cast iron is listed for electric smooth-top, electric coil and gas. The flat base contacts the surface well, but lift rather than slide the pan to avoid scratching the glass top.

How do I clean and store it?

Hand wash with warm water and a brush, dry it fully on the stove, then rub in a thin layer of oil. Avoid long soaks and dishwashers, which strip the seasoning.

How does it compare with a bare cast iron skillet?

The pan itself is standard cast iron; the glass lid is the main difference. It adds covered cooking and visibility that bare skillets lack, at the cost of a lid that cannot take broiler heat.

What can I cook in it?

Searing steaks and chops, frying eggs and potatoes, baking cornbread, and covered braises or steam-finished dishes. Keep long simmers of tomato or vinegar-based sauces for enameled or stainless pans.
