By the early 19th century, most Georgian and Victorian coal-burning fireplaces had a cast iron hob grate with iron surfaces to one or both sides of the grate.
Most rooms had a fireplace, though those in the bedrooms were rarely used.
Some designs were available over for several decades and even in the late 19th century.
The grate was polished to a dull sheen using black lead. This was applied very sparingly and then polished vigorously. An alternative was a thin coat of matt black paint, a coating of wax, and then polished.
