The stamped or drawn aluminum articles are made by the process described in
the latter part of Chapter II. Aluminum is susceptible of deeper drawing with

Some stamped aluminum ware is "spun", that is, after the utensils are stamped
they are placed on rapidly revolving chucks which are shaped to fit the inside
of the article and the workman presses tools of various shapes against the outside.
In utensils like coffee-pots or kettles, the top is turned in by the spinning

by pressing an iron tool against the utensil as it revolves.
Attaching spouts to stamped articles, such as teakettles or coffee- or teapots,
