The Front of Stoves, and similar bright works in cast iron, are first ground on large grindstones, and then buffed on large revolving buffs upon which a coating of emery has been fixed by glue. They are sometimes finished by a hand rubber used as a spokeshave having a piece of leather supplied with fine emery and oil, but the rubbers suspended from the ceiling at the end of a powerful spring, are also very judiciously employed in these large works. See the end of the article Burnisher.
Fire Irons are often cast in iron that is afterwards rendered malleable; which is a rapid way of producing beautiful form, combined with strength and a certain measure of flexibility, see vol. 1, page 259, the works are afterwards case-hardened, that they may admit of a better lustre, and which is generally given by grindstones, glazers, buffs and brushwheels, much the same as in cutlery but on a larger scale.
