Cowen Brick.
The Cowen Brick - probably the best brick in the world.

As with the well known lager advert the title caption may be tongue in cheek but in the case of Joseph Cowen's fire bricks (and industrial gas retorts) it might just be true for they were certainly among the very best. From his brick-yards in Blaydon Burn premier quality fire bricks and award winning retorts were made and exported all over the world.

Below left Cowen's High Yard (Yard No. 1) and right, the Low Yard (Yard No. 2) in their heyday and beneath as they are in November 2013.
The High Yard is fairly intact but the Low Yard has just a few dilapidated fragments remaining.



Let us start at the beginning. Bricks have an ancient pedigree. They are a man made ceramic (baked clay) block used in masonry construction and they are known to have been used as far back as 7500 BC in the Middle East. There is evidence of their use in China in 2000 BC and in Europe from the times of the ancient Greeks and Romans. The British industrial revolution saw a massive increase in brick manufacture and usage, accelerated in particular by the gradual transfer from hand moulded bricks to mechanised mass production in the early nineteenth century.
The clay for bricks was usually found under coal seams. This was a convenient coincidence as the coal needed to bake the bricks was readily at hand. Masonry bricks contain - -
silica (sand) 50/60% by weight
alumina (clay) 20/30%
lime 2/5%
iron oxide - up to 7%
magnesia - up to 1%.
Compared with the various types of bricks for normal building purposes a special category is that of fire brick. These are used to line furnaces, kilns and such like and need to withstand very high temperatures without crumbling. These have an aluminium oxide content that can be as high as 50-80% (with correspondingly less silica).
The craft of brick making began in Blaydon Burn around 1730 and even 70 years earlier fire clay was being excavated from the burn and taken to Paradise, on the north side of the Tyne, to make bricks (Bourn). Anthony Forster began his brick making business in the burn soon to be joined by his brother in law Joseph Cowen (later Sir Joseph 1800 - 1873) in a successful partnership. They made fire bricks and also specialised in industrial gas retorts which were of superb quality and by 1844 these retorts were made as a single integral piece rather than from several parts. The retorts attracted much attention in the Great Exhibition in London (a huge world trade fair) in 1851 and the International Exhibition, also in London, in 1862. There an eminent gas engineer, Mr Lowe, commented enthusiastically on the exceptional ability of the Cowen product to withstand very high heat due to freedom from iron achieved by great care in blending different clays and due to following the Chinese practice of leaving the clay for years exposed to all weathers, turning it frequently over, whilst trained employees removed rogue fragments that might degrade the clay. The Blaydon Burn fire clay was, by good fortune for Cowen, absolutely ideal for the purpose – it was just about the best you could get. Lowe went on to say “Along with extreme care in the manufacture of the products all this is the secret of Cowen's fame”. Eventually Cowen bought out Forster and continued to expand the business helped by a superb product, an increasingly international reputation and spiralling demand.


The son Joseph Cowen Jnr (1829 – 1900) took on the running of the business. By now there were two brickworks - Yard 1 on the burn just west of Winlaton and Yard 2 at the north eastern (Blaydon) end of the burn near the confluence with the Tyne.
Just as an aside – it is legend that Cowen Jnr, who was a commited political activist of radical views, used consignments of bricks to send illicit materials to his radical contacts around Europe. The political satirists nicknamed Joe Cowen Jnr "The Cowen Brick" - a wry comment on his unswerving political views and his renowned family business.
Consignments of Cowens fire bricks and gas retorts were exported all over the world – particularly Europe and countries forming part of the then British Empire. He also produced the Lily Brick (a normal building brick) from his Lilley Drift Mine and Brickworks at nearby Rowlands Gill and High Spen. Many local buildings, terraced rows etc. built with the distinctive light buff Lily Brick are still extant around Tyneside. Even after over 100 years they show no signs of deterioration or spalling due to frost that is typical of some poorly made modern bricks.
The Blaydon Burn brick yards continued on into the 1960s when the supply of suitable clay began to run out. This and cheaper, though inferior, competition gradually brought this famous family business to an end. Nowadays only a few isolated fragment of Yard 2 remain but Yard 1 is still fairly intact being used as a vehicle maintenance depot and storage yard. The buildings stand proud as an epitaph to a golden age.


Older bricks were stamped COWEN and prior to automated production were hand moulded. A good moulder could make in excess of 2500 bricks in a day. Later bricks were stamped COWEN M - I've read that these were produced some time after 1926 at the Low Yard site but in contradiction I've elsewhere read that Cowen M signified the bricks made by automated production (M for manufactured) which replaced the hand moulded method in the mid 1800s. I don't know which explanation, if either, is correct.



Dates. I believe the business existed under the name of Joseph Cowen & Co from 1823 to 1904. The lower yard became operational in 1838. I'm advised the firm then passed into other ownership of Priestman Collieries Ltd, who took control of the other Cowen holdings too. This would be shortly after Joseph Cowen Jnr passed away but all the locals knew it as Cowen's Brickyard, right up to eventual closure in the 1960s and even today when reminiscing about it.

They're everywhere!

I the spring of 2013 I was contacted by Susumu Mizuta, a Japanese researcher studying architectural history. He told me of Cowen fire bricks collected on Amami-Oshima island located south of Japan. He has researched a sugar factory constructed there, and Cowen's bricks were excavated from the site of the factory. The sugar factory was one of earliest modern factory in my country, equipped with modern sugar machines in a brick building built under the superintendence of British engineers and constructed around 1866. The building was completely destroyed long ago and any there are no remains but the fire bricks are now preserved in the local museum. Sincere thanks to Susumu for this information and for sending the photos just below.
PS. He is still trying to establish the origins of the Stephenson brick (see photo) also found at the site.


In the autumn of 2013 I was contacted by Kathryn Archer of Hobart, Tasmania, Australia. She had just uncovered a Cowen fire brick in a cottage she is renovating. The cottage was built in May 1900. Sincere thanks to Kathryn for this information and for sending the photos just below. They show the brick and the fireplace. The brick was hidden under paint behind a wood burning stove.



In the late summer of 2016 I was contacted by Gavin Edmond Hodgkinson resident in Germany. Whilst on holiday in Guadeloupe he found a Cowen brick, see picture below. Whilst now a French region, the British held the islands of a number of occasions and British bricks will have been on board their merchant ships as they were also ideal for ballast. At this particular sugar refinery on the island they had been used to build underground vaulted cool storage rooms, the actual sugar refinery building itself, and the chimneys. Sincere thanks to Gavin for supplying this information.



In April 2018 I was contacted by Flint Benson of Washington State found this Cowen 4 brick in a nearby creek. It was from an 1890-1920 cedar shingle mill. He traced the brick back to an old kiln there (see photo). There were other bricks there too, “Livermore” California, “Atlas” California, “Bonnybridge” Scotland, “Tcarr” England, “Kilgaurd” Abbotsford BC and “Clayburn” Abbotsford BC. Amazing! We both wonder why the '4' on the brick. Anyone know? Thanks to Flint for this information.



My thanks to Stephen Kucharski of Oregon, USA who contacted me June 2018 to advise of this Cowen brick in woods near the small town where he lives. He is trying to find out how it came to be there. Could it be related to old gold mining activity in that locality? Whilst researching the Cowen brick he has found there is one at Alcatraz in San Fransisco.



My son found a Cowen 4 brick in Blaydon Burn in late July 2018. Earlier Flint Benson reported finding one in Washington State, USA. We would like to know the significance of these different numbers if anyone can throw any light?
