Latest Patents

Helen holds a patent for a unique glass composition that absorbs infrared and ultraviolet light. This soda-lime-silica glass features a neutral tint and contains between 0.3% to 0.7% by weight total iron, expressed as FeO. The formulation also includes selenium, cobalt oxide, and a ferrous iron content, ensuring a specific ratio of ferrous iron to total iron ranging from 21 to 34. Additionally, nickel oxide and titanium oxide may be added to enhance the glass properties. The resulting glass, with a nominal thickness of 4 mm, achieves a visible light transmission of at least 70% and a direct solar heat transmission that is at least 12 percentage points lower than the visible light transmission. The inclusion of the mineral wuestite in the glass batch formulation is preferred for providing the necessary iron content.
