Abstract
A method of forming glass containers, including the steps of drying a stream of air, passing the dried air into a vacuum-insulated mixing chamber, evaporating liquid cryogen in the mixing chamber, allowing the resulting cryogen vapor to mix with the air to form a mixture at a temperature below -20.degree. C., passing the gas mixture into a vacuum-insulated manifold, and causing the gas mixture to flow from the manifold and into the insides of glass containers being formed in molds to cool the containers.
