Alternate Names: Lead(II) Chromate
||If this formula is not unified correctly please contact us. |
In nature lead chromate exists as the mineral crocoite. It has monoclinic brilliant-red to orange prismatic crystals. Crocoite decomposes below 1000 degrees to lead oxide and green chromic oxide.
The brilliant reds, oranges, vermillion, and yellow colours achieved in lead-chromium glazes are due to precipitation of crocoite crystals. However lead chromate material is very toxic.
