The old Venetian Diamond was formed by impressing soft glass in a metal mould, as follows:—the first gathering, A, is solid, and afterwards covered by a second gathering, as B; this is expanded by blowing in the usual manner, and being rewarmed, is blown into the projecting pillar-mould, C, and when further expanded, impresses the Glass ball as D; the pillars are pinched together by the pucellas, E, at equidistant points, into the diamond form, E and F, one by one, until the whole of the projecting straight pillars become diamond pillars. Equally good effects are produced by modern Glass-makers in a more direct manner, by making brass open-and-shut, or dip moulds, so as to give at one operation the entire diamond impression, thus saving the tedium of forming each diamond separately with the pucellas. Some of the Venetian caraffes, with handles and loose stoppers, have Glass ornaments laid in lines vertically upon the diamonds, pinched and raised up in parts, in uniform patterns, perhaps more illustrative of industry than taste.
