Once you are done setting up the pour site, it's time to actually pour the piece. Put on all of your required safety gear and heat up the crucible with your metal. This is also the stage where this process gets its name as when you pour the metal into the foam pour cup and form, the metal will be dissolving the foam form while simultaneously replacing the negative space it creates with metal. This is also where the vents created earlier come into play as they allow for the escape of the now gaseous Styrofoam fumes from the pour site.
