Object Lessons is a series of short, beautifully designed books about the hidden lives of ordinary things. Pause and look around: you will see that you are surrounded by glass. It reflects and refracts light through your windows; it encircles a glowing filament above you; it's in a mirror hanging on the wall; it lies shattered in a dented corner of an iPhone-you're drinking water out of a pint glass. Taking up a most common object, rarely considered because assumed to be transparent, John Garrison draws evocative connections between historical depictions of glass and emerging visions that see.
