It has been noted that the crizzling of the glass, particuarly on the interior of the present dish, suggests a Kangxi period dating as glass production at this early stage tends to have an excess amount of alkali in the preparation, which causes the decomposition of the glass, known as crizzling. Varying and controlling the amount of alkali creates opaque, translucent or transparent glass.
The strong European style in the design of the present dish was probably influenced by the Jesuit missionaries who assisted at the imperial workshops, particularly the Dutch Jesuit, Ferdinand Verbiest (1623-1688), who was known to be close to the Kangxi Emperor. On closer inspection, the delicate foliage and swirling tendrils clearly show the ragged lines made by diamond-point engraving as opposed to the use of the wheel-cut technique which would have produced a smoother finish. It has been suggested that the ruffling of the surface caused by an overall scratching method is typical of a Dutch technique, rather than the long parallel scratches that characterise Venetian diamond-point engraving, cf. The Minor Arts of China, IV, Spink & Son, London, 1989, p. 84. Diamond-point engraving was also used on a pair of clear glass cups which are similarly decorated with birds and grapevine, and dated to the Kangxi period, in The Corning Museum of Glass, and illustrated by C. Brown and D. Rabiner, Clear as Crystal, Red as Flame, China Institure in America, New York, 1990, no. 11.
