Black Japanned Finish Screws, Fasteners and Fixings

Often referred to as Japan Black, or Black Japan, but sometimes Japan Lacquer or Brunswick Black, this lacquer or varnish is mainly used on iron or steel, but can be suitable for a number of other materials that are used in the creation of fasteners and fixings.

Consisting of mostly an asphaltic base dissolved in naphtha – a flammable liquid hydrocarbon mixture – or turpentine, which is a flammable fluid obtained by the distillation of resin from pine and other live trees, amongst other varnish ingredients such as linseed oil. The lacquer is applied directly to parts of metal and then baked for up to an hour.

Previously, a black japanned finish was popular within an automotive finish due to its durability. Ironware was often japanned black for decorative reasons, and to also render it rustproof and therefore suitable for carrying water.

In the past, it was also used to protect metal objects such as sewing machines, hand planes and builders’ hardware.

Wolverhampton and Bilston are well known for their manufacture of black japanned wares, especially the most successful, John Martson, who’s japanning factory began to make the famous Sunbeam bicycles.
