Use of the equipment. Parts for condensers may have a wall thickness of Vie to l/& in., whereas tower sections or large socket pipes can be made s/8 in., or even heavier. The limits of blown Ware are approximately 15 gal. for necked vessels and 12-in. diameter for socket pipes.The limits for pressed and blown articles are, of course, subject to upward revision, as the present sizes represent less than two j^ears' development work. As an example of the enlargement of sizes, it is of interest to remember that less than a year ago a 10-liter Pyrex dish was an achievement, whereas to-day the 24-in. dish has a capacity of 30 liters.
