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.
Lay on your right side and then lubricate the tip of the enema tube and also your anal region with some lubricant. Take a deep breath and insert the tip of the tube into your rectum, no more than 3 inches. After it is inserted you can then slowly open the clamp to allow the coffee mixture to flow into your rectum.
