The works were situated on Cock-pit Hill, at the commencement of Siddal’s Lane. The site is still known as the “Pot Yard.” It is distinctly marked on some of the old maps of Derby, and appears to have stood immediately opposite the “Cock-pit” itself--an octagonal building, with a spire-roof terminated with a vane. Buildings existed on this spot as early as 1610, and at that time probably were employed for the making of the rough ware of the period. In the last century they seem to have formed three sides of a quadrangle, and to have been of considerable extent. In 1772 it is thus spoken of in “A Short Tour in the Midland Counties;” after speaking of the china works, the writer says:--“Here is also a pottery, and I was showed an imitation of the Queen’s ware, but it does not come up to the original, the produce of Staffordshire.” In 1780, in consequence of the failure of the Heaths (who were bankers and men of property, besides one of them being at one time the partner of Duesbury, and, later, the owners of these pot works), the Cock-pit Hill Pottery sold off its stock of goods. The following is one of the announcements of this sale.-- “TO THE MERCHANTS, TRADERS, AND DEALERS IN EARTHENWARE. “To be Sold without Reserve (and considerably under the usual wholesale prices) at the Derby Pot Manufactory a large quantity of Earthenware, being the whole stock in trade of that great and extensive Factory commonly known by the name of the Derby Pot Works, consisting of an assortment of Enamelled, and Blue and White useful China, a large quantity of Enamelled Creamware and plain Cream Tea-table-ware, a great quantity of White Stone and Brown ware. “N.B.--The aforesaid Earthenware, &c., will be opened for sale on the 4th and 6th of April and continued every Tuesday and Thursday until the whole is disposed of; on which days (but no other in the week) a proper person will attend the sale. The Earthenware will be sold in different lots, and is well worth the notice of Pot Carriers in and about the neighbourhood of Coleorton Moor. No less a quantity than two horse loads will be sold to any one person.”
