Setted flasking stone

Boiling water 4-5 min.

Soften wax

Separation of the flask: If all undercuts were properly blocked-out in the investing procedure, no breakage of the hellls will take place
Lift-out the base trays carefully

Flash out the wax residue with hot water

Make sure that all the teeth are in place for not affected occlusion and balance

Clean the mould with a detergent or wax solvent
