METAL MELTING AND POURING USING
THE CASTING BASE AND VACUUM PUMP
21
EXPERT TIP:
In this section, you will need a silica crucible, a torch, motor oil, and a container
with water large enough to fit the flask(s).
Rest the casting base bottom on a flat surface and place the casting base on top of it.
Apply a small drop of oil to the casting base top, spread it
evenly, and center a paper gasket on it. The paper gasket
will create a vacuum seal once you turn on the vacuum
pump (replace the paper gasket as needed).
EXPERT TIP:
After using the casting base, it is normal for
oil to accumulate inside its bottom. Clean it using paper
towel as needed.
Remove the flask from the kiln using the crucible tongs.
Place it on the center of the casting base system, on top
of the paper gasket.
