Excerpt from The American Journal of Dental Science, 1891, Vol. 24The next point is the amount of pressure required to produce a dense tough plate. After locking the ¿ask, remove it from the press as quickly as possible and place it in a large bench vice, Close as tight as possible, and leave it there to become cold. You can easily understand that I was not long in crushing a half-bushel Of cast-iron ¿asks, then I experimented with malleable-iron ¿asks to the tune Of four hundred dollars, -they proved unsatisfactory, brass was too soft, bell metal too hard and brittle. My ¿asks are now made Of bronze a little softer than bell metal.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
