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. MSDS pdf  Due to fluctuating prices in the raw materials market, any price increases will be confirmed with you before your order is charged or shipped. 11/24 |
