This pigment does not have a pigment code yet. We bought this color from Holbein as part of our explorations into lead white alternatives. While Titanium is amazing for so many things, its opacity can make it a bit challenging to work with for some applications. It is nice to have some white colors that borrow from the working properties of zinc or lead without the toxicity of lead. Based on a rare Siberian mineral called Tausonite, this is an interesting and less opaque white than Titanium. Currently this pigment is used by Holbein in Ceramic White.
