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.
Do a lower volume enema on the first day and then proceed to doing a full enema the next day to begin some serious colon cleansing. You will use anywhere from one cup to one quart, or more, of water for your first low volume enema.
