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.
There are two types of enemas: the high enema, given to cleanse the large bowel, and the low enema, to cleanse only the lower bowel. (Illustration by Electronic Illustrators Group.) enema, intended to cleanse only the lower bowel, is administered at lower pressure, using about 500 cc of fluid. Oil retention enemas serve to lubricate the rectum and lower bowel, and soften the stool. For adults, about 150-200 cc of oil is instilled, while in small children, 75-150 cc of oil is considered adequate.
