MASS-PRODUCED GLASS CONTAINER WITH VISIBLE LIGHT SHIELDING AND FABRICATION METHOD THEREOF USING RECOVERED POST-CONSUMER GLASS

Abstract: a fabrication method of a mass-produced glass containers with visible light shielding using recovered post-consumer glass, the method comprising obtaining successive batches of raw material for glass manufacture, each batch including between 80% and 100% by weight of a mixture of pieces of soda-lime-silica recovered post-consumer glass with a heterogeneous chromatic composition predominantly transparent; mixing to the successive batches of raw material visible light shielding additives including at least cobalt oxide, nickel oxide, manganese oxide, chromium oxide and iron oxide; melting the successive batches of raw material and automatically manufacturing therewith the mass-produced glass containers with a glass thickness of at least 2 mm through an automatic blow molding process; automatically detecting and rejecting manufactured containers with permeability against visible light between 450 nm and 680 nm wavelength above 3% or above 1%.
