View Full Version : Zinc white/mixing white OP?

Do any of the oil pastel manufacturers offer a zinc white (i.e. mixing white) PW4 stick?
I've checked the Sennelier and Caran D'Ache OP color charts and they only have titantium white PW6. I haven't been able to find any useful information about pigments on other manufacturer's web sites.

Hi Chuck. A warm welcome to the forum. As far as I know Titanium oxide is a much stronger pigment and covers better than Zinc oxide. Oil pastels need the strength of the Titanium white.
It depends on what working qualities you're looking for. Titanium white is a highly opaque pigment, whereas zinc white is much more translucent (and cooler in color temperature) than titanium white. Now unlike most other oil pastel manufacturers, Sennelier does not only use translucent and transparent pigments, but they do not add opacifiers to such pigments, thus allowing each pigment to retain its unique qualities. But they do not make a zinc white oil pastel, at least not yet.
