Potbank Dictionary - definitions and explanations of those fabulously mysterious words, terms, phrases and dialect of the Potteries. 

Established in 1976, still going strong, still being added to and still being tweaked.

Here are those strange and very special terms, such as saggar makers bottom knocker, wedging, and ginneter that were, at one time, very common in the Potteries potbanks. There's also the special dialect of the district.

With almost nearly, but not quite, 1800 definitions, the Potbank Dictionary explains and demystifies the peculiar words collected during a lifetime in potbanks. Some are specific to a particular factory, others are quite common in the district. Some are quite technical. Much of this language is disappearing as potbanks are closed, as skills are lost and as manufacturing methods change. 

This is by no means an academic work but it is accurate and is rather quirky in places! Originally established in 1968 and first published by Gladstone Pottery Museum in The Friends Broadsheet Newsletter in January 1976. 

Compiled by Terry Woolliscroft and constantly updated since then. This website, launched in May 2012, is archived for preservation by the British Library.

This film, on YouTube, is a wonderful introduction to the area and how the language of the Potteries evolved. Incidentally, the guy in the image is not me but you will see him in the film.

What is a POTBANK?

A place where pottery is made. 

It is the entire pottery factory including all the buildings and the yards involved in the potting process, from sliphouse to warehouse. According to the late Robert Copeland: “The term Potbank has been used for generations ... I believe that it derives from the days when Josiah Wedgwood was unable to meet the demand for his creamwares so he sub-contracted to other potters to make his shapes in the body of his specification, and to hold these stocks in their own warehouses for him to call upon as he required them. These warehouses were called banks. The term does not imply that the pottery was on a hillside nor by a canal or river.”  More here>

"Five Towns. An introduction to the glorious heritage of the Staffordshire Potteries"

Britain on Film. Directed by Terry Bishop. 26 mins. The five towns of the Staffordshire Potteries region are passionately described in the film. As well as lovingly detailing the area’s famed production techniques, the documentary also looks at the challenges of post-war reconstruction in the region.






What are BOTTLE OVENS and KILNS?

Huge and imposing, towering and daunting, brick-built, bottle-shaped structures, up to 70 feet high, essential in the making of pottery. The red-hot heart of the Potteries of Stoke-on-Trent.

In 1939 there were about 2100 bottle ovens and kilns, or, strictly speaking, bottle-shaped structures of various types used for firing pottery ware or its components. They dominated the landscape of the Potteries of Stoke-on-Trent. In 2025 there are fewer than 50 still standing complete with their chimneys. None will be ever be fired again. The Clean Air Act of 1956, and their delicate condition have put paid to that.

At the multi-award-winning Gladstone Pottery Museum, in Longton, Stoke-on-Trent, there are 4 bottle ovens and one bottle kiln. There are also two bottle ovens, next door, at the Roslyn Works. This is the most important and precious group of buildings in the Potteries.

Don't get confused! 

Bottle ovens or bottle kilns are the terms applied to a variety of brick-built, coal-fired ovens and kilns used in the north Staffordshire pottery industry. They are often used interchangeably and confusingly. The names derive from the characteristic shape of the brick-built hovel or chimney stack utilised by such structures.  But they cover a range of different types and uses. 

Some were used to fire pottery to a biscuit or glost state - these were known locally as ovens. Others which were referred to as kilns were used specifically in the decorating process (muffle kilns), or the preparation of raw materials for ceramic bodies (calcining kilns) or glazes and colours (frit kilns). 

There was also variation in the means of construction. For example, not all types had independent hovels, many were enclosed within buildings and had the chimney stack (the ‘neck’ of the bottle) constructed directly on top of the firing chamber or supported on an outer ‘skeleton’ structure. 

In addition, by the late 1800s, both updraught and downdraught (in which heat was re-circulated around the firing chamber) types were in use within the industry.

What is BONE CHINA?

BONE CHINA A smooth textured and extremely white firing pottery body.  Translucent and very strong. It is unique in that it contains a high proportion of calcined bone ash and biscuit fires at approx 1220 C. A type of porcelain.

Around fifty percent of the body recipe contains calcined cattle bones. Invented at the Spode factory in Stoke-on-Trent around 1800. The recipe contains about 50% calcined cattle bone, 25% china clay and 25% china stone. The bone used at Spode was more specifically the shins and knuckle bones of oxen. (Lower grades of bone china, not from Spode, may have used all or some bones from sheep or goats.  But definitely not horses.)  The bones are calcined at temperatures up to 1000 C before being ground to a fine powder and used in the bone china recipe. Bone china is extremely hard and intensely white.

The Invention of Bone China:  The Spode company, under Spode I and Spode II, is credited by potters, collectors, researchers and other experts with having perfected the bone china formula before 1800.
