As it has been suggested there was a frequent use of metal mounts upon leather and pottery vessels and stone-ware jugs and flagons were silver mounted-sometimes being silver-gilt. Many such pieces often of genuine authenticity sell for hundreds of pounds when brought under the hammer, for they are very rare. Most of these mounted stoneware flagons are of mottled ware, ornamented in relief, like the famous bellarmines of a slightly earlier period. The potters of those days courted royal favour and freely used the royal arms or monogram, the Tudor rose and other loyal emblems, many of the pieces exhibiting considerable skill in modelling. The silver rims and the covers of these jugs are generally hall-marked, thus fixing their dates, and distinguishing them from ancient jugs and flagons which have been mounted with silver in more recent times, this of course making a material difference in their value to a collector. Some of the rare Fulham ware jugs and cups were silver mounted, although possibly many so mounted have been given this additional ornament many years after they were made. Many vessels of this old pottery were similar to Cologne jugs and the grey wares of several Continental towns, Dutch imitations and foreign copies of the antique -silver mounted and impressed with marks little under-stood by the English or American collector are rather deceptive and should be avoided unless expert skill in identifying their true origin is available.
