Antimony Oxide White
PW11
Alternate Name
Timonox
Pigment Description
A very toxic white. It is made with antimony and barium sulfate. However as a historical aside (since it is so rarely used) it interesting to note that it was often mixed with zinc oxide, so that is perhaps an additional consideration for oil painters.
