Pigment instability

From: Christopher Weeks <ceeweeks>
Date: Monday, August 21, 1995
Can anybody shed any light on the problem of colour instability
in certain pigments, notably red mercuric sulphide (vermilion),
tetroxide of lead (red lead), and lead carbonate (white lead), under
Q-switched YAG laser radiation (wavelength 1064nm)?
