    Yes, those parts are important. If you don’t properly measure the investment and water, when you pour the metal into the flask it may come out too soft. This can cause the investment to crack, and then the metal comes out the bottom of the flask, possibly injuring someone or causing a fire. And if you don’t vacuum it, you could end up with bubbles left in it. Bubbles in the investment will turn into raised lumps and bumps all over your finished castings.
