My grandfather worked with iron all his life. In a shed near his place of business was a square brick item about 4' x 4' and about waist high. It is filled with sand and has a pipe running through it that can be turned. Someone told me that he would pump hot air from his shop to this thing and he would smelt iron here. Have you ever heard of this? What would this be called? I can send a picture. I won't let anyone tear it down because it has historical significance to me. Can you tell me how this works?
