Look around you! Glass is everywhere: the mirror where you brush your teeth in the morning, the test tube in your science class, and your cup of juice on the dinner table.But what do you really know about it? Where did it come from?To find out, you have to travel all the way back to ancient Egypt, where glass was first in use.Beautiful illustrations give a sense of the time and place as you span the globe and thousands of years to see glass's use expand from small pots, to bottles, to cathedral stained-glass windows to telescope lenses and more! Lots of diagrams detail the step-by-step processes of glassmaking through the ages.Another vivid and informative book from a master of explanation, Bruce Koscielniak.
