Big Role for Rock

Here's my question: who the hell ever first thunk up this elaborate, non-intuitive processing of gypsum, a rock out of the ground? The ingenuity of mankind and our genius ancestors is awesome and baffling.

Before sheetrock was invented, builders used plaster made out of ground lime to coat walls. And going even further back, the Romans used volcanic ash. So the idea of using ground-up rock of some kind on walls is pretty old. The revolutionary thing about sheetrock was the idea of sandwiching the ground gypsum between paper. That made installing it relatively unskilled work.

Demolition is also easier and less messy. Have you ever ripped out a lath and plaster wall for a remodeling project?

Is this why they say the walls are paper thin? 😉
