Abstract
A mold for shaping end portions of glass tubes has first and second mating members which define a contoured bore into which the heated tube fits. Each member has a longitudinal bore from which extend radial bores opening into the interior cavity of the mold containing the tube. Each member also has radial vent bores for venting gases and vapor to the outside. Each longitudinal bore is connected to a lubricant, such as water, supply, which is applied to the surface of the tube through the radial bores.
