King Street Works 

These works were established in the latter part of last century [18th C.] by Mr. Shelley, who was succeeded by Mr. Marsh, from whom they passed to Messrs. T. & J. Carey. The productions of these firms were the ordinary Rockingham ware and common classes of earthenware ; Messrs. Carey also occupying two other manufactories at Longton. 

They were next held by a company, and about 1850 passed into the hands of the present proprietor, Mr. John Edwards. The goods now produced are semi-porcelain and white granite for the American markets. Until 1856 Mr. Edwards produced china in addition, but this has since then been discontinued. Mr. Edwards is patentee of a process for making thimble pins; and he also, in 1859, took out a patent for "improvements in stacking or holding biscuit, earthen, china, and glossed ware for firing" by means of "a ring frame or holder, with a rim or flange projecting inwardly, so as to occupy the whole or part of the centre of the ring."
