The invention provides a method of making a vessel having a sculptural interior, comprising attaching a textile core to the air inlet port of an I.S. machine, inserting a gob of molten glass into a mold to surround the textile core, applying compressed air to press the molten glass around the textile core, applying compressed air to inflate the textile core creating the bottle, allowing the bottle to cool sufficiently to withdraw the core from the bottle, and withdrawing the textile core from the bottle.

A glass forming machine includes a blank mold hanger and a blank mold. The blank mold hanger includes a blank mold hanger half that supports a blank mold half and provides cooling fluid to at least one axial cooling channel defined in the blank mold half. The blank mold hanger half defines at least one cooling fluid outlet, which is in fluidic communication with the at least one axial cooling channel of the blank mold half. The blank mold hanger half additionally includes at least one flow control valve that is remotely controllable and configured to selectively adjust a flow of cooling fluid through the at least one axial cooling channel of the blank mold half. A method of cooling a blank mold is also described.

A method of producing flint glass using submerged combustion melting is disclosed. The method includes operating a submerged combustion melter such that combustion products are discharged from one or more submerged burners combusting a combustible gas mixture that comprises fuel and oxygen. An oxygen-to-fuel ratio of the combustible gas mixture ranges from stoichiometry to 30% excess oxygen relative to stoichiometry, a temperature of a glass melt in the submerged combustion melter is between 1200 C. and 1500 C., a residence time of the glass melt is maintained between 1 hour and 10 hours, and a specific throughput rate of molten glass discharged from the submerged combustion melter ranges from 2 tons per day per meter squared of cross-sectional area of the submerged combustion melter [tons/day/m.sup.2] to 25 tons/day/m.sup.2. A method of forming glass containers from the molten glass discharged from the melter is also disclosed.
