  • Method for preparing pre-reacted raw material batches for the production of synthetic silicates
    Patent number: 7937970
    Abstract: A method for preparing pre-reacted synthetic batches, with a low content of carbon dioxide, for the production of glass formulas, which comprises mixing stoichiometric amounts of substances, containing molecular systems of silica-sodium, silica-sodium-calcium, silica-sodium-magnesium, silica-calcium-magnesium, silica-sodium-calcium-magnesium and mixtures thereof, having reaction temperatures which do not form a liquid phase, that are selected from invariant points or from points on a line connecting invariant points of phase diagrams of said molecular systems, to complete a desired molecular formula; adding cullet to the mixture; and calcining the mixture to a reaction temperature which do not form a liquid phase and wherein the CO2 is liberated.

  • Method for preparing pre-reacted batches of raw materials for the production of glass formulas
    Patent number: 6358870
    Abstract: A method for preparing pre-reacted batches of raw materials substantially free from carbon dioxide for the production of glass formulas, comprising: mixing stoichiometric amounts of substances containing molecular systems of silica-sodium, silica-sodium-calcium, silica-sodium-magnesium, silica-calcium-magnesium, silica-sodium-calcium-magnesium and mixtures thereof, having reaction temperatures which do not form a liquid phase, which are selected from invariant points or from points on a line connecting invariant points of phase diagrams of said molecular systems, to complete a desired molecular glass formula.

  • Method for the manufacturing of glass sheets
    Patent number: 4801321
    Abstract: A method of manufacturing glass sheets from molten glass contained in a vertical drawing chamber includes the step of placing a stratified liquid layer on the mass of molten glass, the stratified liquid layer comprising at least two phases of densities different to each other, and vertically drawing a glass sheet from the glass mass through the stratified liquid layer.
