From 1885 at the Mount Pleasant Works, in the Tinkers Clough area of Hanley. 

18 Feb 1886 they registered "A jug of tapering and compressed cylindrical form, moulded gadrooning and grooves at the base and level rim, snake entwined loop handle from the neck to lower body." Cartlidge & Matthias. Hanley, Mount Pleasant Works , Tinkers Clough - registered design 43435.  

By around 1888 they had moved into the purpose built Chelsea Works. 

The Chelsea Works boasted "modern and costly steam driven machinery, everything that is possible being done by steam power, steam printing, steam drying, etc. etc." (1893 article on Cartlidge & Matthias). 

Around 1911 a Bertram Swinnerton partnered with Walter Lindley in buying the Chelsea Works from Cartlidge & Matthias. "It was only a small factory with just two ovens but they employed about 30 people and it had the reputation of being the best equiped factory in Hanley" (The Swinerton Saga - August 2006 p.271)
