Casting Flask Temperature: Additional Information

Peter Johns, the inventor of Argentium® Sterling, sent me the following information:

"We have found that flask temperature is not critical but metal temperature is. Metal temperature should be between 1740 F and 1800 F. Flask temperature should be what is normal in standard sterling for size and weight of the piece."

"If you are casting into a steel mould I always file all sides of the ingot before rolling. I always thought this was normal practice but I recently found somebody who was not doing it and they were not getting good results."
