ABSTRACT
The articles manufactured are very brittle and full of air bubbles. With copper a green tint is given to glass; but the Shísha-gar is ignorant how to impart any other, and he cannot mould vessels.
The workman makes the various articles by fixing a mass of molten glass on the point of an iron tube, and by alternate blowing and rolling fashions it as he wishes. The size of the vessel is regulated by a pair of iron pincers held in the right hand, while the iron tube is being twirled in the left.
