Gary,

Thanks for the reply. I usually store my pigments dry, but it seems many companies that supply these pigments are starting to ship them in paste form, and I just wondered why they do that? And yes, I keep a colour, or recipe jounal as well as tile composites.

I didn't know Naples yellow was a "heavy metal" type pigment. What is ut made out of? Naples yellow is the one of the colours I use most in obtaining flesh tones,......

Thanks
