Clay & Glaze Chemicals / H - L / Iron Sulfate (copperas)



Iron Sulfate (copperas)


  • 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.
