Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.

Overall, the use of TiO2 in factory settings plays a crucial role in enhancing the quality, performance, and appearance of a wide range of products. Its unique properties make it an invaluable ingredient in various industrial processes, allowing manufacturers to create high-quality, durable, and visually appealing finishes. As technology continues to advance, the demand for TiO2 is expected to grow, further solidifying its importance in the manufacturing industry.
