Potclays began underground, in Staffordshire fireclay.

Potclays tells its own story from the ground up. “The Potters Coal and Clay Company was established as a clay mining company in 1932 at Brownhills, South Staffordshire, under the Directorship of William Noake,” its history says. It ran mines at Brownhills and around Walsall, “extracting and processing high-quality, pale firing fireclays that we still use to this day.” Companies House records the mining company, The Potters Clay & Coal Co. Limited, as incorporated in 1935 and still active.

The clay business came next. “Potclays Limited was founded in 1941 by Warbreck and Helen Noake,” the company says, and the register confirms an incorporation in January 1941. In 1947 it moved into the old Downings brick and tile works at Etruria, a short distance from Stoke’s centre, in Stoke-on-Trent — the district named by Josiah Wedgwood for his own works — and in 1965 it bought the neighbouring Albion Works, a former teapot factory. Jonathan Noake joined in 1969; a merger with Harry Fraser Ltd followed in 1976. James Otter joined in 2013, the company says, the latest of the family to come into the business.

It remains a family firm. The register lists Jonathan Noake as holding more than three-quarters of the company, with Rebecca Otter — Becky, the fourth generation, the company says — and James Otter among its directors. Potclays describes itself as a “family-run firm in Stoke-on-Trent with over 90 years experience,” with two manufacturing sites, at Etruria and Brownhills, and 36 employees.

Fireclay, St Thomas, and a Cadbury panmill.

Potclays’ distinctive raw material is the one it began by mining: the pale-firing fireclays of South Staffordshire, which it says it still uses. Its range includes a “Fireclay 320” powder and the St Thomas family of stoneware bodies, in oxidising, reduction and white versions, firing between 1150 and 1300°C. Fireclay — the clay found with coal seams, valued because it withstands heat — is a different material from the ball clays of Devon and Dorset or the china clay of Cornwall, and it gives Potclays a connection to its own geology that few clay houses can claim.

The company’s history has the texture of the Potteries. It says its panmills — heavy grinding mills — were “once used at Cadbury’s to grind the cocoa nibs,” bought in the 1960s. It says it has built kilns “since the early 1980’s,” and that it is the “Only authorised importers into the UK for Shimpo & L&L Kilns” — Shimpo, the Japanese wheel maker, and L&L, the American kiln maker. Since 2024 it has also distributed the Cowley Double Drive wheel. These are its own accounts.

Its business, in other words, runs from a mine to a kiln: a clay house that also sells the machines and fires to work its clay.

Where clay comes from.

Stoke-on-Trent became the Potteries because of what lay nearby — coal to fire kilns, and, from further away, the clays that made white ware possible. The British Geological Survey records that ball clay “became important during the late 17th and early 18th centuries when Staffordshire potters, notably Josiah Wedgwood, recognised the attributes of ball clay for the manufacture of whiteware pottery.” Britain’s ball clay, it says, “is confined to three relatively small areas, all located in south west England” — the Bovey and Petrockstowe basins in Devon and the Wareham basin in Dorset — and its china clay comes overwhelmingly from the St Austell granite in Cornwall, about 88 per cent of sales when the BGS last surveyed it. The scale is industrial: UK ball-clay sales ran at about a million tonnes a year between 2005 and 2010, the BGS says, with 83 per cent exported in 2008, and the country’s china-clay sales fell from a peak of 2.78 million tonnes in 1988 to 1.36 million in 2008, about 30 per cent of them to ceramics. Two companies dominate: the BGS named Sibelco and Imerys as the UK’s only ball-clay producers in 2011, and Imerys says its Devon and Dorset ball-clay operations can be traced to the late 1700s.

The name “ball clay” itself, a 1975 government dossier says, “is believed to be derived from either the original method of extraction, in which the clay was cut on the floors of open pits into approximately 25 cm cubes or ‘balls’ weighing about 15-17 kg, or the digging implement, known as a tubal.” And the BGS explains why clay houses exist at all: blending “is very important as it reduces the natural variability of the clays.” A clay body is a recipe that turns variable raw materials into something a potter can rely on.

Potclays is unusual in having started at the raw end of that chain, as a miner of its own Staffordshire fireclay, before becoming a maker of blended bodies. Clay houses typically buy raw clays and blend them, as the BGS describes; Potclays’ history put it, for a time, on both sides of that transaction. Its neighbour in this round, Valentine Clays, names a Dorset ball clay in its own product copy — the other side of the Potteries’ supply chain.

A date that belongs to the mining company.

Potclays’ tagline, “Supporting Potters Since 1932,” uses the mining company’s date rather than the 1941 founding of Potclays itself — a fair choice for a family business that counts the two as one story, and one we have explained above. Its other line is a triad: “Quality · Reputation · Worldwide” — three words chosen to reassure a buyer at a distance, in markets well beyond Stoke.

The logo is a single dark forest green, the same colour the website uses as its theme. For a design guide, that consistency is the point: one colour, one family, one district. Potclays does not need a heritage story invented for it; it has a mine, a works on a famous site and four generations of the same name on the register.

For this guide we use that green, taken from the company’s own logo file, with a pale fireclay tone and a traditional serif. Nothing of the Potclays logo is reproduced.
