Abstract
A method of making a hollow container-shaped glass article composed of soda-lime-silica glass includes forming a particulate feedstock comprised of pulverized soda-lime-silica cullet particles into a hollow monolithic glass container preform without melting the cullet particles. The hollow monolithic glass container preform has a container shape that includes a wall defining an interior containment space and an opening to the interior containment space and, upon formation, has a temperature above the glass transition temperature of the soda-lime-silica glass. The hollow monolithic glass container preform is eventually cooled into a hollow, amorphous soda-lime-silica glass article, such as a partially-formed container or a finished container, that retains the previously-established container shape.
