+--- Thread: Uranium pigment in tilework (/showthread.php?tid=1668)
Uranium pigment in tilework - Paul Ferguson - 01-04-2025
"In what may be the first-ever use of uranium in Iran, yellow pigment created from uranium oxide ("(oksid-e uran") was used frequently in Qajar tilework. The oxide was imported from Europe and sold to artisans by alchemists ("meshshaq"). The pigment fluoresces under UV light."
