cements, jewellers' - Cements, Jewellers'
cements, jewellers' - It sometimes happens that jewellers, in setting precious stones, break off pieces by accident; in this cage they unite the parts so that the joint cannot be easily seen, with gum mastic, the stone being previously made hot enough to melt it. By the same medium, cameos of white enamel or coloured glass are often joined to a real stone as a ground, to produce the appearance of an onyx. Mastic is likewise used to cement false backs or doublets to stones, to alter their hue.
