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.
Start by adding one cup of coffee to the enema bucket and one cup of clean water. If you want a larger volume in your enema, you can add up to a total of 3 cups of water. Some people recommend that the coffee enema should be no more than 2 cups of liquid, while others recommend 3 or 4 cups of liquid. The temperature must be body temperature.
