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.
Enema supplies needed for this procedure include an enema bag, enema tube, enema nozzle, tube clamp, and water. The enema bag holds all the liquid needed for the procedure. An enema tube connects the bag to the nozzle that is inserted into the anus. The tube clamp allows the user to control the flow of water into the rectum, slowing or stopping it as needed. When inserting the enema nozzle into the anus, lubricant typically should be used to minimize pain and discomfort.
