"The Overhouse Works — Wedgwood Place. 

In 1787, the record runs, ‘Thomas Wedgwood, Manufacturer of Cream-coloured Ware and China glazed Ware, painted with blue’ worked the Overhouse Pottery at Burslem. The old works were situated at the back and side of the Overhouse, with entrance in Wedgwood Place, where that street joined Scotia Road.

Early in the nineteenth century, the Overhouse Works were occupied by Goodfellow & Bathwell, who were succeeded in 1819 by Edward Challinor, and from about 1828 by William Pointon. In 1856, they passed to Morgan, Williams & Co., afterwards to Morgan, Wood & Co. who, in 1861, were succeeded by Allman, Broughton & Co., and later by Robinson, Kirkham & Co. 

In 1869, the old works were entirely taken down and a new and extensive manufactory was erected with all the latest improvements of machinery and appliances, the jiggers all being driven by steam-power and the drying stoves heated by exhaust steam. 
The rebuilding, after half a century of active occupation by one person, was thus commemorated in ornamental scroll stonework over the entrance:
‘Edward Challinor commenced business here A.D. 1819, and rebuilt the premises A.D. 1869.’ 

The new manufactory was opened in 1870 by Ralph Hammersley, who removed here from the Church Bank Pottery at Tunstall and who had previously been engaged for twenty years with Mr. Challinor. In 1833, the firm’s style was changed to Ralph Hammersley & Sons and as such remained until sold in 1905 to T. Gater. 

Twentieth-century owners include Gater, Hall & Co., King & Barratt, and Barratts of Staffordshire Ltd.
The goods produced by Hammersley were the ordinary description earthenware in services of various kinds and the usual classes of useful articles which (besides a good home trade) were shipped in large quantities to the United States, Canada and Sweden. Stoneware jugs were also produced. The mark was the initials R.H. & S. in various forms until 1905."

Poole Pottery operated concurrently with Royal Stafford at the Overhouse Works 

Poole Pottery takes its name from the costal town of Poole in Dorset. It had no connection with Thomas Poole of Tunstall, Stoke-on-Trent.

Poole Pottery (2007) Ltd was a company that took control of Poole Pottery after it came out of administration in 2007. 

The company was owned by Lifestyle Group Ltd, which also owned Royal Stafford Tableware. Operation of the two brands was concentrated at the Overhouse Works, Burslem, Stoke-on-Trent. 

Poole Pottery continued to have financial difficulties and in 2011 Denby Holdings acquired the company.  In December 2012 a voluntary liquidator was appointed.

Poole Pottery then moved manufacturing to the nearby Middleport Pottery, Burslem which Denby Holdings had purchased in 2011.
