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.
Types of Enemas. Cleansing Enema. There are three types of cleansing enemas: the large volume enema, the small volume, enema, and the packaged, disposable enema. Normal saline is normally used for a cleansing enema because it is isotonic solution and therefore, does not cause electrolyte imbalance, unlike the tap water.
