Paper coated with red lead

The "Annals of Medicine" article was titled "Cinnabar" and was by
Berton Roueche. It appeared in the New Yorker dated 8 December
1986. The cinnabar had 8.9 parts per thousand of lead and the fabric
of the ancient Peruvian tapestry had a lead concentration of 380
ppm. The article speculates that the ancient pigment sample was
adulterated with red lead in modern times by someone who needed to
add some weight to get a better per ounce price.
