Messrs. Clementson Brothers,
Earthenware Manufacturers, Phoenix and Bell Works,
Broad Street, Hanley (Established 1832).

The potter's art being undeniably one of the most ancient, as well as one of the most useful crafts the world knows, our readers require little or no apology from us for introducing a series of articles on this subject in the present work, and among the many important houses devoted to the manufacture of earthenware in Hanley, the firm of Clementson Brothers, of the Phoenix and Bell Works, Broad Street, must be cited an a leading example. 
The business was established as far back as the year 1832 by the late Mr. Joseph Clementson,J.P., who was succeeded on his decease by his sons, and the business has been for many years energetically and successfully carried on by them, but Mr. Baxter -who is a grandson of the founder - still trading as "Clementson Brothers" has now succeeded to the business. 
The Phoenix and Bell Works are comprised in a substantially-erected two-storied building, with considerable frontages to both Broad Street, and Bethseda Street, and, in addition to tho office entrance, there are two archway entrances to the works, the general idea conveyed by the appearance of the whole structure being one of stability and importance. 
The firm manufacture almost entirely for the North and South American and West Indian markets, doing at the present day a very large trade with those sources, their productions comprising white, granite, mid printed goods, such as dinner, tea, and toilet ware, etc, and they are milking a special feature at the present time of printed toilet ware, and also printed and plain semi-porcelain ware, and, having lately added a valuable plant of modern machinery to this end, they are in a position to compete favourably with any other house in the Potteries in these particular goods. The Bell Works throughout are fitted with all the most modern and improved machinery und appliances; seven ovens - four of which are glost and three biscuit - are kept constantly going, together with the usual hardening-on and enamelling kilns, etc.; the average number of hands employed by the firm being 275.
Every attention is paid to sanitary matters throughout the works so as to ensure the health and comfort of the operatives, and the general relations existing between Messrs. Clementson Brothers and their numerous workpeople are of the most harmonious and satisfactory character. 
In addition to the manufacture of earthenware, Messrs. Clementson Brothers are also millers, having a very large mill from which they supply other manufacturers with.
