Enamel sign

Benjamin Baugh created the first purpose-built factory for making such signs in Selly Oak in 1889 — the Patent Enamel Company.

[4] The use of enamel signs died down around World War Two due to cost and use of metals needed for wartime efforts.

Some specialty enamel sign construction companies exist today; however, they do not produce on a mass market scale.

[4] Enamel signs are created by layering powdered glass over a base such as rolled iron.

[4] Common damages to enamel signs include scratches, bullet holes, and crazings.
