Our hematite, chromite and pyrite-based products are used for coloration and as performance additives in container glass, flat glass and automotive glass. Densfil is used in commercial building glass cladding to impart solar control and aesthetics and add color and ultraviolet protection to tinted windshields, back-lights, quarter-lights, and sunroofs for the heavy and light vehicle automotive markets. Additionally, Densfil, Pyritemax and Chromox are used in the production of container glass to achieve green and amber color bottles in the furnace. Relatively small additions color the glass but do not affect the basic properties of the glass except for changes in the lower solar light and energy transmission.
