Staffordshire blue brick is a strong type of construction brick, originally made in Staffordshire, England.

The brick is made from the local red clay, Etruria marl, which when fired at a high temperature in a low-oxygen reducing atmosphere takes on a deep blue colour and attains a very hard, impervious surface with high crushing strength and low water absorption.

Brickworks were a key industry across the whole Black Country throughout the 19th and 20th centuries, and were considered so important that they were designated as a reserved occupation during World War Two. The Black Country was a major producer of clay for brickmaking, often mined from beneath the famous 30 foot Staffordshire coal seam. This is an ancient industry, and probably took place from the 17th century at least, however the industry really took off in the 19th century.[1] A key date is 1851 when the Joseph Hamblett brickworks was founded in West Bromwich, which became one of the largest producers of the famous Staffordshire blue bricks. Other sites produced these too, including Albion in West Bromwich, Cakemore works at Blackheath, Springfield at Rowley Regis, John Sadler, Blades and New Century at Oldbury, Coneygre at Tipton and Bentley Hall near Darlaston.[2]

This type of brick was used for foundations and was extensively used for bridges and tunnels in canal construction, and later, for railways. Its lack of porosity makes it suitable for capping brick walls, and its hard-wearing properties makes it ideal for steps and pathways. It is also used as a general facing brick for decorative reasons. Staffordshire Blue bricks have traditionally been "Class A" with a water absorption of less than 4.5%.
