Solution to Last Week's Puzzler
Architecture Puzzler #227

Question

If I told you this common building material is manufactured from CaSO4-2H2O, what product would I be referring to?

Answer

CaSO4-2H2O is gypsum ore and, along with paper, is the main component of gypsum wallboard. In North America, about 30 billion square feet (2.8 billion square meters) of wallboard are produced each year.
