After the top part of the flask is filled with a mixture of half stone and half plaster and it has hardened place the flask in boiling water for 10 minutes to melt the wax.

Try putting vaseline inside your flasks .This makes deflasking easier and keeps the flasks cleaner.When investing cut down your model to the size of your waxed denture and cut off any unnecessary teeth on the model.This will make flasking a lot easier .

Will we put it in boiling water immediately after this step?
