Hi George,


A fellow tempera painter recently told me that "Afghan lapis lazuli will grey out" with age.  I understand that less well-washed grades of lapis have much less blue chroma and appear greyish from the start; and I've heard that acidic conditions can dull a genuine lapis lazuli to grey.  But I haven't heard of a high grade lapis lazuli pigment turning grey merely from aging.  Your thoughts?


Thanks, Koo
