Sweet iron oxidises on contact with the moisture in the mouth and the air. The oxidation gives a sweet taste that naturally stimulates the production of saliva. This corresponds to the effect of a sugar given to the horse at the beginning of the session but allows this sweet taste to be diffused throughout the work. Consequently, this alloy allows a good acceptance of the bit and helps the horse to make contact with the mouthpiece. The oxidation modifies the appearance of the bit as the sessions progress.
This alloy does not require any specific maintenance other than a daily rinse with water.
