Resumen–En este artículo se discute el descubrimiento del litopón fosforescente en dibujos a la acuarela por el artista americano John La Farge, fechados de 1890 a 1905, y la historia del litopón en la industria de los pigmentos a finales del Siglo XIX y principios del Siglo XX. A pesar de tener muchas cualidades deseables para su uso en pintura para acuarela o pinturas al óleo blancas, el desarrollo del litopón como pigmento para artistas fue obstaculizado por su tendencia a oscurecerse con la luz solar. Su disponibilidad para los artistas y su adopción por ellos sigue siendo poco clara, ya que por lo general los catálogos comerciales de los coloristas no eran explícitos al describir si los pigmentos blancos contenían litopón. Además, el litopón se puede confundir con blanco de plomo durante el examen visual, y su fosforescencia de corta duración puede ser fácilmente pasada por alto por el observador desinformado. A la fecha, el litopón fosforescente ha sido documentado solamente en otra obra mas: una acuarela por Van Gogh. Además de la historia de la fabricación del litopón, el artículo detalla el mecanismo para su fosforescencia, y su identificación con la ayuda de espectroscopía de Raman, y de espectrofluorimetría.

On the other hand, the chloride process involves heating the ore with chlorine gas to produce titanium tetrachloride. This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide
This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxide This intermediate compound is then refined further and reacted with oxygen at high temperatures to yield titanium dioxidetitanium dioxide is prepared from factory. The chloride process generally results in a higher purity product and is more energy-efficient, but it requires sophisticated equipment and handling due to the corrosive nature of chlorine gas.
