Trudy及John Cohen伉儷，藏品編號B64，約1976年從上處獲得 Typically characterised by mottled or variegated shades of orange, red, green and yellow, this type of glass is known as 'realgar' for its resemblance to the vividly coloured but highly toxic mineral. Realgar ironically carried strong associations with longevity, as it was believed to have been used by Daoist alchemists in their pursuit of Immortality. Its brilliant hues made it especially prized by artisans, who employed the mineral itself in the creation of works of art and also sought to replicate its distinctive appearance in glass. Indeed, 'realgar' glass is arguably among the earliest coloured glass to have been produced in China, as supported by the existence of examples bearing the Yongzheng mark, as well as other examples present in Europe by the mid-18th century. For a detailed discussion of the early development of 'realgar' glass, see H.Moss, V.Graham, and K.Tsang, A Treasury of Chinese Snuff Bottles: the Mary and George Bloch Collection, vol.5.1, Hong Kong, pp.138-140. A related realgar-imitation glass snuff bottle, 18th century, is illustrated in The Baur Collection: Chinese Snuff Bottles, Florence, 2007, pp.148-149, no.H52.
