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.
To use the rectal enema: 1  Shake the rectal enema before using it. 2  Lie on your left side with your right knee up toward your chest, leaning forward slightly. 3  Gently squeeze the bottle until it is empty, and then remove it from your rectum. 4  For best results, hold the enema liquid in your rectum for up to 10 minutes.
