Police Report # 07-4810. Elegant Regency Period Tureen, Sheffield Plate Platter with Hot Water Warming Base and matching Domed Cover. The size of the oval form which both pieces are engraved, attributed to Matthew Boulton, the Sheffield process and the architectural elements of the engraving are very well detailed. H:16" L:25" The History of Sheffield plate is a layered process of silver and copper that was used for many years to produce a wide range of household articles. These included buttons, caddy spoons, serving utensils, candlesticks and other lighting devices, tea and coffee services, serving dishes and trays, tankards and pitchers, and larger items such as soup tureens and hot-water urns. Almost every article made in sterling silver was also crafted by Sheffield makers, who used this manufacturing process to produce nearly identical wares for a less cost. Sterling silver alone would have been far too expensive for the emerging middle classes to afford, so there was a continual search in mid-18th century England for a suitable replacement. Thomas Boulsover, of Sheffield's Cutlers Company, provided the solution in 1743. While trying to repair the handle of a customer's decorative knife, he heated it too much and the silver started to melt. When he examined the damaged handle, he noticed that the silver and copper had fused together very strongly. Experiments showed that the two metals behaved as one when he tried to reshape them, even though he could clearly see two different layers. He then carried out further experiments in which he put a thin sheet of silver on a thick sheet of copper and heated the two together to fuse them, when this was hammered or rolled to make it thinner, the two metals were reduced in thickness at similar rates. Using this method, Boulsover was able to make sheets of metal which had a thin layer of silver on the top surface and a thick layer of copper underneath. When this new material was used to make buttons, they looked and behaved like silver buttons but were a fraction of the cost. This new "double sandwich" form of Sheffield plate was developed around 1770. It was used for pieces such as bowls and mugs that had a visible interior, it consisted of a sheet of silver each side of a piece of copper. Later on, borders were applied with a U-shaped section of silver wire to conceal the copper which can be felt as a lip on the underside. Following the invention of German silver, around 1820, it was found that this new material also fused well with sheet silver and provided a suitable base metal for the Sheffield process. Because of its nearly silver color, German silver also revealed less wear, or "bleeding", when Sheffield-made articles were subject to daily use and polishing. Sheffield plate is fairly rare today, as after about 1840 it was generally replaced with electroplating processes. Electroplating tends to produce a "brilliant" surface with a hard color, so Sheffield plate is still used in cases where a softer color more like natural sterling silver is desired. . Matthew Boulton was born in Birmingham in 1728. His father was a toymaker in Snow Hill, specializing in buckles and buttons. In 1749 the father took the young Matthew into partnership in his already flourishing business, and put him in charge of its management. After Mathew 's father had dies he resolved to build his reputation on jewelry, silverware and plated goods of the highest quality. To this end he recruited the best designers and craftsmen he could find, however cheaply it might sell, should be of the best possible quality that could be achieved for the price. He was also the first person outside Sheffield to take up the manufacture of Sheffield plate, effecting product improvements in the process. This Tureen is an example of excellent style and design with a cartouche on one side with a crest.
