Clyde Pottery Marks
The Clyde Pottery used a large variety of marks to identify its wares. The marks often correspond with particular patterns and hence the mark name and pattern are often the same. Certain marks are used during specific periods thus making it possible to date pieces. Normally the pottery was consistent in using the terms C.P. Co. and C.P.Co. Ltd. but during the Thomas Shirley period of ownership from 1841 until 1857 the abbreviation T.S. & Co. is also found.
