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.

One of the most significant advantages of TiO2 is its transparency. Transparent TiO2, also known as transparent pigmentary titanium dioxide or TTPO, has gained popularity in recent years due to its ability to provide both opacity and transparency. This unique property makes it suitable for applications where both functional and aesthetic properties are crucial, such as in automotive paints, cosmetics, and certain types of plastics.
