An expected and alarming article about the hazards of using zinc oxide in painting. Research shows that “combinations with a wide number of other pigments, including Titanium White, does not appear to mitigate zinc’s brittleness”, and that “lowering the percentage of zinc to even these levels* did not seem to make the blends any safer to use” (* previously the manufacterer had reduced it to 2%, but further review showed the need to completely removing zinc oxide).
