The Chelsea manufacture of china is said to date from _Cenvirons_, 1745-49, but a species of porcelain was produced in a glass factory at Chelsea in 1676, established there by some Venetians, patronised by the then Duke of Buckingham. Clay from Dorsetshire, sand from the Isle of Wight and kaolin, and chinastone from Cornwall and Devonshire, were employed at this factory. An anchor sometimes barbed, and at other times with amulets, and one within a double circle; as also a triangle, with the name "Chelsea," and the date "1745" beneath it, were the marks chosen to distinguish this ware. On the finest specimens the anchor is gilt, on those of second quality in red, brown or purple upon the glaze. [Illustration] The porcelain of Chelsea bears some resemblance to that of Venice of about the same date--the Cozzi period, 1780--which is natural, the founders of the manufactory having been Venetians; and the porcelain produced there stands amongst the very first of our English ceramic works in every respect, ranking higher than that of Bristol. The workmen were originally procured from Bow, Burslem and other works; the china manufacture being carried on at first by William the Duke of Cumberland and Sir Everard Faulkenor, the latter dying in 1755 or 1758, and the former in 1765, when Sprimont became sole proprietor. Three blemishes, or spots, characterise the china of this factory, appearing at equal distances where the glaze has been removed, apparently by contact with what the article rested upon. The work executed at the Chelsea factory ranked in the highest place that was ever attained at others in this country. It was greatly admired by Wedgwood, and was scarcely inferior to the best at Sèvres. The whole contents of the manufactory were sold by auction by M. Sprimont on his retirement; Mr. Duesbury purchasing the house, etc., and the remainder of the stock was sold by Christie and Ansell in 1779. One of the earliest of the Chelsea marks is here given showing the date; and two anchors side by side and one inverted, in gold, is only found on the finest examples. [Illustration] The early productions of Chelsea were of soft paste, and the glaze was thick and creamy, much of the white ground being left without decoration. The pieces with the _bleu de Vincennes_, the peacock green and turquoise blue, copied from the Sèvres ceramists, were of later date. Those of claret-colour are very rare. All these self-coloured examples are highly gilt. (_To be continued._) RINGS LOST AND FOUND. BY DORA DE BLAQUIÈRE.
