Antiques slideshow – 19th-century watercolour and German porcelain

Item one: A set of six German porcelain coffee cups, sent in by Valerie O’Donnell The set was made circa 1860. The pattern is a well-known one, found most famously at Royal Copenhagen but also used by several German and Austrian factories. Value will be unaffected by the manufacturer’s identity, which we unfortunately could not determine from the images. Value: £60-£80. Photograph: Valerie O’Donnell

Item two: A ruby glass bottle vase, sent in by Joanne Fleming The present owner found the vase in an attic in Providence, Rhode Island. This appears to be more ruby coloured than cranberry glass (which is of a pinker hue). The enamelled decoration is hand painted, but with quite thin (inexpensive) gilt. This type of glass has been made in many countries including Germany, Italy and England. This particular example probably dates from the first half of the 20th century. A charming piece, even though this type of glass has become unfashionable with collectors. Value: £25-£40. Photograph: Joanne Fleming

Item three: A silver filigree-inlaid copper dish, sent in by David Broad This plate was probably made in Syria or Egypt in the 20th century because there is a signature in the centre of the dish which appears to be a copy of a tughra (an Ottoman sultan’s signature). This kind of piece, if it is from Egypt, would sometimes be classified as “Cairo-ware”. Value: £30-£50. Photograph: David Broad

Item four: Early 19th-century watercolour featuring a coastal scene, sent in by Leslie Barrett The present owner bought this at a car boot sale a few years ago. This watercolour certainly looks like it was created around the time of British painter Thomas Girtin (1775-1802), and is clearly a work of reasonable quality. Though the best of Girtin’s own works can still command prices comfortably into the thousands, interest in this kind of academic, early British watercolour has waned in recent years and this appears to be a work by an unidentified hand of the period and loosely of the style of Girtin. Value: £100-£200. Photograph: Leslie Barrett

Item five: A cameo glass bowl, sent in by John Hartshorne This cameo glass bowl, made of yellow glass overlaid in green and etched with vine branches, was probably manufactured by Stilart, Romania, after 1992. The bowl resembles the famous French Art Nouveau cameo glasswork made by Gallé and Daum in Nancy in the early 20th century. However, the colour, finishing and technique of this bowl reveal it is actually a modern replica in the manner of Stilart, a Romanian firm that has produced Gallé and Daum imitations in large quantities since 1992. The marks on the bowl are pseudo marks that vaguely resemble the marks of the firms mentioned. Value: £25-£35. Photograph: John Hartsthorne
