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.
If you are nervous about administering an enema, start with a low volume enema (about 500ml) for your first try. This will relieve any anxiety about the procedure, and then you can proceed to take in a higher volume of solution. You might be surprised how much the colon can actually take in.
