This is a range of Flat Tarnished Copper available from G&H Brassware.
They are copper plates that have been tarnished at the point of manufacturing, then lacquered for protection. This gives it a non-uniform finish. No two plates are the same!
Please note: Not suitable for freshly plastered walls. As these plates are made of copper they are not suitable for newly plastered walls. Please allow 6 months before fitting to freshly plastered walls. This ensures the walls are fully dried out and won't cause tarnishing to the plates.
Don't forget these plates are flat, so require deeper back boxes than standard plates. The manufacturer recommends the following back boxes:
