My family’s business, in the modest Colorado town where I grew up, was a foundry. For the uninitiated, a foundry is like a steel mill. Its basic operation is to melt ore (in our case, iron, brass, and aluminum) in a furnace, pour it into molds, and thereby produce metal castings. Our family joke was that my parents were “in the iron and steel business” – my mom would iron while my dad would steal. (I’ll spare you the rest of the foundry jokes.) Foundry work is hard, hot, dirty, and notoriously dangerous. Our furnace room temperature was 140 degrees fahrenheit.
