It is usually made of masonry, brick, or stone.

How does a fireplace draw air?

A fireplace creates a column of heated gas inside the chimney. As that air rises, more heated air from the fire is pulled after it. The result is a draft — a steady flow of smoke and hot gases — up the chimney. … As the hot gas rises, it pulls fresh air into the pile of burning fuel.
