  • Patent number: 11370686
    Abstract: 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.

  • Patent number: 11339078
    Abstract: A method of reducing the volume of float bath atmosphere lost from an opening in the exit end of the float bath is described. The method comprises directing a first jet of fluid having a first jet velocity followed by a second jet velocity towards a plane a conveyance for a float glass ribbon. An obstruction in the path of the first jet of fluid causes the jet to change from the second to a third jet velocity. The obstruction may be a portion of a roller positioned outside the opening or a float glass ribbon that has been formed on a surface of molten metal contained in the float bath that has subsequently been transferred through the opening. A float bath having sealing means to reduce atmosphere loss from an exit of the float bath is also described, as is an assembly useful in carrying out the aforementioned methods.
