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.
Subsequent enemas should be tap water only, to rinse out any soap or other chemical solution that the first enema was treated with and prevent irritation of the colon. Do not use distilled water, as it will draw out more of your body's electrolytes through the colon.
