Iron oxide reacts with components such as silicon dioxide in gypsum to produce various colors of gypsum molds, such as bright yellow, reddish brown, brown, etc. At the same time, it can also promote the removal rate of crystalline moisture, improve the hardness and density of gypsum.
 
In addition, iron oxide can alter the crystal structure of gypsum, giving it higher toughness and tensile strength, making it less prone to fracture during use.
