After the pour and safety

#After the pour

The After the pour stage on the Investing & burnout tab takes you from the cast flask to clean metal:

1. Quench and devest, with the wait before quenching for your investment.
2. Pickle the tree to remove oxides and flux, and deal with any fire scale.
3. Cut the castings off the tree.
4. Recover the button and sprues for the next melt.
5. Clean the flask and the work area, and dispose of the spent investment safely.

Then the pieces are ready for finishing.

Never quench a flask with stones cast in place. Let it cool. See Casting with stones in place.

#Safety checklist

The Safety checklist covers the main hazards of a casting day:

• Silica dust from investment powder: wear a proper dust mask when mixing.
• Ventilation and burnout fumes.
• PPE for the melt and pour: eye protection, gloves and clothing.

The checklist can be printed with the burnout sheet.
