  • Iron Sulfate is a soluble material often used in raku and low fire soda applications. 
  • If calcined at 1652*F iron sulfate becomes anhydrous iron sulfate, also referred to as crocus martis, Fe2O3-FeSO4. 
  • This form of iron sulfate is used at all temperatures and helps in creating colors ranging from soft yellows to dark purple-browns.
