PrO2 (Praseodymium Oxide)
Notes
-Used for lemon yellow stains in combination with zircon. These stains are not as powerful as antimony or vanadium but are flexible.
-PrO2 can be used in reduction firing, even at high temperatures.
-While it is toxic, it is not as dangerous to use as either vanadium or antimony.
-Different glaze chemistries can produce brighter yellow coloration.
-PrO2 glazes do not tolerate contamination of other coloring oxides well.
