Models and samples in the form of bookplates, drawings, prints, seals, medals and pattern dishes were utilised by European merchants to illustrate the extensive range of European designs and decorative patterns available to Chinese decorators. Pattern plates were decorated with multiple designs around the rim and armorial devices and monograms in the centre. Each pattern was marked by a number to easily illustrate a merchant's chosen style from the range available. On the back of the piece is the anglicised name Syngchong, probably belonging to a Chinese merchant, and used to denote the calligraphic styles available to a discerning customer. During the eighteenth century sample dishes became particularly popular due to adoption of standardised patterns and armorial shields on export porcelain. Pattern plates played a significant role in the transmission and imitation of decorative styles, increasing manufacture and the delivery of export porcelain.
