Excellent question. I'm using vermilion pigment, which is mercury sulfide, and toxic until it's mixed down into the tempera. I used titanium white instead of lead white, otherwise I would have had to do the same every time I mixed a color with white. I limited my toxicity exposure to just the vermilion.
why did you use a mask to mix the red paint?
