THE PROCESS OF CREATING MACHINE MADE GLASS MARBLES
Working by myself, I can only
produce a limited number of marbles at a time. I employ the same hand gathering
processes that were used at the M.F. Christensen & Son Co., Akro Agate, Peltier
Glass, and The Christensen Agate Co..
Each marble starts as a bit of
glass manipulated on a punty rod. The glass is heated up as hot as possible and
then cut from the punty rod with a pair of glass shears - left image. Once the
gob has been placed into the rollers, it is then rolled into a sphere shape -
middle image. After the marble is done forming, it falls off the end of the
rollers into a metal chute - video below. From there I pick the finished sphere
up with tongs and then place it into an annealing oven to slowly cool over a 12
hour period.
The image on the right shows the
entire
William J. Miller glass marble making machine from Peltier Glass. Built in 1923;
the 3650 pound marble machine is capable of producing marbles from 5/8" up to
1.125". To the best of my knowledge, this is the world's oldest surviving glass
marble making machine.
