Royal Doulton

The Royal Doulton company began as a partnership between John Doulton, Martha Jones, and John Watts, as Doulton bought (with £100) an interest in an existing factory at Vauxhall Walk, Lambeth, London, where Watts was the foreman. They traded as Jones, Watts & Doulton from 1815 until Martha Jones left the partnership in 1820, when the trade name was changed to Doulton & Watts. The business specialised in making salt glaze stoneware, including utilitarian or decorative bottles, jugs and jars, much of it intended for inns and pubs. In 1826 they took over a larger existing pottery on Lambeth High Street.

The company took the name Doulton & Co. in 1854 after the retirement of John Watts in 1853, and a merger with Henry Doulton and Co. (see below), although the trading name of Doulton & Watts continued to be used for decades. For some of the 19th century there were three different businesses, run by the sons of John Doulton, and perhaps with cross-ownership, which later came back together by the end of the century. By 1897 the total employees exceeded 4,000.

Pipes and other utilitarian wares

Manufacturing of ceramic sewage pipes began in 1846, and was highly successful; Henry Doulton set up his own company specialising in this, Henry Doulton and Co., the first business to make these. This merged with the main business in 1854. His brother John Junior also later set up his own pipe-making business. Previously sewers were just channels made of brick, which began to leak as they aged. The 1846–1860 cholera pandemic, and the tracing by Dr John Snow of the 1854 Broad Street cholera outbreak in London to a water supply contaminated by sewage led to a huge programme of improving sewage disposal, and other forms of drainage using pipes. These and an expanding range of builder's and bathroom fixtures and products remained important product categories for Doulton into the 20th century. Metal plumbing items such as taps and cast iron baths were added to the range later. Kitchen stonewares such as storage jars and mixing bowls, and laboratory and manufacturing ceramics, were other long-standing specialities. Further facilities were set up for making these in Paisley in Scotland, Smethwick, St Helens near Liverpool, Rowley Regis in England, and eventually Paris.

Decorative wares

By the 1860s Henry Doulton became interested in more artistic wares than the utilitarian ceramics which had grown the business. British stoneware had languished somewhat in artistic terms, although Wedgwood and others continued to produce jasperware and some other stonewares in a very refined style, competing with porcelain. The Doulton wares went further back to earlier salt-glazed styles, with a varied glaze finish. This "gave stoneware an entirely new impetus, realizing the potential of the material".

As the company became interested in diversifying from its utilitarian wares into more decorative objects, it developed a number of earthenware and stoneware bodies. The so-called "Lambeth faience" (from 1872) was "a somewhat heavily potted creamware much used in decorative plaques and vases", often with underglaze painting. Other bodies were called "Impasto" (1879); "Silicon" (1880), "a vitrified unglazed stoneware decorated with coloured clays"; "Carrara" (1887), white earthenware, also used as architectural terracotta; "Marquetrie" (1887), "marbled clays in checker work", then glazed; "Chine" impressed with fabrics to texture the clay, these burnt away in the kiln.

By 1871, Henry Doulton, John's son, launched a studio at the Lambeth pottery, and offered work to designers and artists from the nearby Lambeth School of Art. The first to be engaged was George Tinworth followed by artists such as the Barlow family (Florence, Hannah, and Arthur), Frank Butler, Mark Marshall, Eliza Simmance and John Eyre. John Bennett was in charge of the "Lambeth faience" department until he emigrated to America in 1876, where he had success with his own pottery.

Doulton was rather unusual in that most of the Lambeth studio pieces were signed by the artist or artists, usually with initials or a monogram incised on the base. Many are also dated. Until 1882, "every piece of the company's art stoneware was a unique item" but after that some pieces were made in batches, as demand grew.

There were initial production difficulties in producing the "art" pieces; at first they were fired in the open kiln with other wares, but later saggars were used. They were not especially profitable, sometimes not profitable at all, but there were huge profits in other parts of the business. Like other manufacturers, Doulton took great trouble with the wares submitted to international exhibitions, where they were often medal winners. The period 1870–1900 saw "the great years of Doulton's art stoneware", which remains popular with collectors.
