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.
This will often relax the sphincter or soften the stool enough so that the tube or tip can be inserted and the enema can be administered. Four types of enemas are commonly administered: cleansing, return-flow, medicated, and oil-retention. The type of enema prescribed depends on the indication. A cleansing enema can be either large- or small-volume. It acts by stimulating peristalsis by instilling a solution or irritating the mucosa of the colon.
