The majority of foundries specialize in a particular metal and have furnaces dedicated to these metals. For example, an iron foundry (for cast iron) may use a cupola, induction furnace, or EAF, while a steel foundry will use an EAF or induction furnace.
PROCEDURE. If you will be giving the enema to yourself the first thing you should do is set up the area for the procedure. Make sure the hook is suspended at the proper height (18-24 inches above the rectum). Then place a pad or bath towel where you will be lying down.
With steady pressure, gently insert enema tip into the rectum with a slight side-to-side movement, pointing the tip toward the navel. Do not force the enema tip into the rectum because you could hurt yourself. Squeeze the bottle until the recommended amount of the drug is inside the rectum.
