I worked the last three weeks helping with an Iron Pour at The Colorado Springs School. The Art Department has built the small cupola (furnace) with which they melt about 1500 pounds of iron in a night, pouring into student molds. Below is a tap, a pour into ceramic molds and a pour into open bonded sand molds. What fun! And all by 15- and 16-year-olds! This is the seventh Iron Pour at CSS in twenty-four years.
We achieve almost a hundred percent success with this exercise.
