Victorian illustration to download showing men at work blowing and forming glass at a glass works. In the background is a huge domed furnace. To the left a man sits in a ‘glass-maker’s chair’, which has sloping arms edged with wrought iron so that he can roll the vessel he is forming back and forth. He shapes it with ‘pucellas’, tongs for forming the mouths of vessels. He is being helped by a boy. To the right a man manipulates molten glass on a ‘marver’, a polished cast-iron slab, to give the glass a regular outer surface. In the centre a man blows glass using a blowing iron. This scene was sketched at Apsley & Pellatt & Co, London, in 1843.
