Among the men of eminence who have been connected with the potteries of Liverpool, besides those named, were William Roscoe, the eminent Art-critic and biographer; Peter Pever Burdett, the engraver, who also worked for Wedgwood, and who introduced the process of transferring aquatints to pottery and porcelain; Paul Sandby, who assisted other manufactories; and other artists of note. It may also be well to say a word or two on those pieces which more than others are considered to be “Liverpool pottery,” and which, indeed, I believe are thought by many collectors to be the only kind ever made there. I allude to the mugs, plates, &c., of cream-coloured ware which are decorated with ships or with flags of different merchants, and signals. These were principally made at the works of Guy Green, in Harrington Street, of whom I have already spoken. Some pieces have the engraving of the lighthouse and flags, with the name, “An east view of Liverpool Light House and Signals on Bidston Hill, 1788.” The flags are all numbered, and beneath are references, with the owner’s names, to forty-three different flags. Another piece with the same date has forty-four flags and owners’ names, showing the addition of a new merchant in that year. Others again, without date, show fifty and seventy-five flags, and are therefore interesting as showing the rapid extension of the port. These pieces are very sharply engraved and printed in black, and the flags on some of the pieces are coloured. WARRINGTON.[6]
