PW5 - Complex Co-precipitate of Barium Sulfate and Zinc Sulfide
Porcelain White is based on a new pigment for Williamsburg, PW 5, a complex co-precipitate of barium sulfate and zinc sulfide more commonly known as Lithopone. Created in the 1870s and for a while a rival to both lead and zinc, it captured some 60% of the market for white pigments in 1928 before declining to 15% by 1945 in the face of a growing dominance by titanium dioxide (Alphen 1998). It holds a renewed interest for us as an alternative to Zinc White, which forms a brittle film and has been linked to issues of cracking and potential delamination when used extensively. Historically known as Enamel, Orr’s, or Charleston White, we chose the one we felt was the most descriptive: Porcelain White.
