This paper is an account of the evolution of machinery used in glass‐making in which the modern methods are contrasted with the old. Gas producers, gas burners and oil burners are discussed. In burning gas a greater efficiency obtains when the air entirely surrounds the gas stream as it enters the fire box. In burning oil the high pressure costs more for installation but is more efficient. The tendency is towards automatic machinery for all glass‐making operations. Many machines are well nigh perfect but improvements are being made constantly. Mention is made of the need of a better alloy for metal molds. In the glass industry labor represents on the average 40 per cent of the cost of the product. In this respect the glass industry ranks thirteenth.
