Glass The Decline in Pressed Glass Prices. Does this offer a good investment or buying opportunity for specialists who know their glass and know the market? Part I. A history and the current market. By John Ainsley In 1979, Colin Lattimore published his pioneering work, English 19th Century Press Moulded Glass, giving collectors, for the first time, line drawings of manufacturers’ trade marks and regis- tered design information on both the kite marks of 1842-1867 and 1868-1883 and the serialised design information from 1884- 1901. A second book, English Pressed Glass 1830-1900, by Raymond Slack extended the manufacturer information relating to pressed glass beyond 1883 to 1900. This was published in 1987 and built on Lattimore’s work. From the twenty years, say, from 1980 to 2000, pressed glass and particularly coloured glass was highly popular, Sowerby table centre sets of nursery rhyme figures reaching 4 figure sums at their peak about ten years ago. Since then prices have seriously declined and should present an investment opportunity, provided the collector buys only the very best and rarest pieces. This should usually mean buying decorative glass such as figures and animals rather than more mundane functional wares. Most dealers and auctions now agree Fig.1.

Editor’s Collection. simplest form nineteenth century press-moulding involved the gathering of a quantity of molten glass and dropping it into a mould. A plunger was then pressed onto the glass such that the object became impressed with the form and pattern of the mould on its outside and the plunger on its inside. Usually the only impressions left on the inside of articles were registration or trade marks. After cooling and solidifying the object was held briefly back in the ‘glory-hole’ to melt away the mould lines (fins) and to polish the finish previously lost to the object through its contact with the metal mould. The press-moulding of hollow ware developed in America in the late 1820s and was quickly imported into England. The first pressing machine was installed by T. Hawkes and Co., Birmingham in 1831 and pressing was underway in the West. Midlands by about 1835. In order to withstand the mechanical process, pressed glass objects were thick and as a consequence heavy. At the time glass was heavily taxed by weight, during manufacture - a tax which Fig.2.

Surface designs were set against abraided backgrounds. Part-frosted patterns became popular. A well known example is the Greek key pattern on a frosted ground registered by Molineaux, Webb and Co, Manchester on the 22nd December 1864. ‘Lacy’ designs were imported from America where the background to various patterns consisted of small hemispherical beads. This technique was particularly effective on commemoratives. The ‘Gladstone for the Million’ design Sowerby Queens Ivory Ware basket registered by Henry Greener of 31st July 1869 is an example.

Indeed in the next twenty years art and industry were to merge. The boundary is not always distinct. There was contemporary recognition of the heights of ingenuity and art achieved by pressed-glass manufacturers and the part played by the mouldmakers. But it was forgotten.
