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.
An enema is a safe, effective, and natural way to cleanse the bowel. It more closely approximates a natural movement than laxatives or suppositories and is much more gentle on the system. Only the last 24 to 36 inches of the digestive tract are involved, as compared to over 30 feet as is the case with laxatives.
