The one surface built for heat.
A fireplace is where a room’s metal has to be honest. Heat finds every shortcut in the making, and the surface people sit closest to is the one that shows it.
Metal near a fire is doing two jobs. The surround and the hearth tray are architectural — they frame the opening and finish the floor and wall around it. The fire panel and the basket are working parts — they sit in the heat, and they are made from thicker material, formed rather than folded, and finished in a way that will not lift or discolour.
Blackened steel is the traditional choice for the working parts because it has nowhere to go: it is already the colour heat would make it. Brass and bronze are used for the surround and the tray, where they are warm to the eye and stay outside the range that would move a finish.
The hearth tray is more engineering than it looks. It has to sit flat on a floor that may not be, take the weight of the basket and the fuel, drain if it is ever washed, and meet the stone or tile around it with a clean line rather than a bead of sealant.
Ornament belongs on the surround and nowhere else. A cast relief, a hand-beaten face or a fluted profile on the surround is the tradition; on the fire panel it fills with soot and cannot be cleaned.
