Stone-in-place casting trees
Remove the flask immediately from the machine. Dip only the bottom part of the tree in cold water and keep under ventilation for 15 minutes. Quench in water.
Trees without stones
Remove the flask within 1 minute after pouring, then quench immediately in water.
Dip in RADIAL solution (50 g/l conc. at 60°C for 2 min.), or in sulphuric acid (10% conc. at 50°C for 5 min.)
