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.
As for enema, I would suggest you doing it when it is most convenient to you. Get a 2 quart minimum enema bag and filter the water. Use it warm and try holding at least 2 quarts at a time. You need to work your way up to it. You will also need to pretty much be empty to hold it all at once.
