Safety summary for jewellers' rouge

A block of jewellers' rouge is made of iron oxide, otherwise known as 'rust'. It is not harmful, we have not been able to find any safety data sheets. It stains (hands, fabric, everything) but this is not a safety issue, and it washes off eventually. Wash stained hands with warm water and soap.
