Patent number: 11919799Abstract: A method of of fining low-density submerged combustion glass includes introducing unfined molten glass produced in a submerged combustion melter into a fining chamber of a fining tank and, further, introducing additive particles into the fining chamber that comprise a glass reactant material and one or more fining agents. The one or more fining agents are released into the molten glass bath upon consumption of the additive particles in the molten glass bath to chemically fine the molten glass bath and the glass reactant material includes one or more materials that integrate into the molten glass bath upon melting. Additionally, the method includes discharging fined molten glass out of the fining chamber of the fining tank. The discharged fined molten glass has a volume percentage of gas bubbles that is less than the volume percentage of gas bubbles in the unfined molten glass introduced into the fining chamber.Type: GrantFiled: May 12, 2022Date of Patent: March 5, 2024Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Earnest Iddings, Nicholas A.

Patent number: 11370686Abstract: A method of fining low-density submerged combustion glass is disclosed. The method involves introducing unfined molten glass produced in a submerged combustion melter into a fining chamber of a downstream fining tank. Additionally, additive particles are also introduced into the fining chamber to release one or more fining agents into the molten glass bath contained in the fining chamber to accelerate the removal of bubbles from the molten glass bath. The fining of the molten glass bath as assisted by the one or more fining agents allows for fined glass to be discharged from the fining tank that has fewer bubbles and a greater density than that of the unfined molten glass introduced into the fining tank. Additive particles that include a physical mixture of a glass reactant material and the fining agent(s) are also disclosed.Type: GrantFiled: October 1, 2019Date of Patent: June 28, 2022Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Earnest Iddings, Nicholas A.

Patent number: 11319235Abstract: In a process for manufacturing glass, a mixture of solid glass-forming materials may be melted by application of heat from one or more submerged combustion burners to produce a volume of unrefined molten glass comprising, by volume, 20% to 40% gas bubbles. A refining agent may be introduced into the unrefined molten glass to promote gas bubble removal from the molten glass. The unrefined molten glass including the refining agent may be heated at a temperature in the range of 1200° C. to 1500° C. to produce a volume of refined molten glass. The refined molten glass may comprise, by volume, fewer gas bubbles than the unrefined molten glass. A colorant material may be introduced into the refined molten glass to produce a volume of molten glass having a final desired color.Type: GrantFiled: October 1, 2019Date of Patent: May 3, 2022Assignee: Owens-Brockway Glass Container Inc.Inventors: Zhongming Wang, Udaya Vempati, Casey Townsend, Earnest R Iddings, Sutapa Bhaduri, Nicholas A.
