The Story of Glass

In the century after the Civil War, the increased use of iron, steel and something not used before in the form and design of buildings was introduced - concrete.  Concrete was actually as old as the Romans, but its use in widespread masonry was not.  Along with new designs in buildings came new uses for glass, bringing the outside inside and the freedom of view.

The story of glass is goes back 1000s of years.  Glass is an ancient material, but transformed over the many centuries to what we use today.  The ancient Egyptians used glass for glazing beads, making imitation precious stones, and even for travel.  Glass-blown vessels were widely used on the Mediterranean before Jesus.

During the Middle Ages, glass became more useful in personal ways like fancy containers, chandeliers and mirrors.  Venice was the glass making center of Europe in the 13th century.  Glass makers' techniques were counted among the treasures of the city and guarded as secretive.  Venetian glass makers perfected a pure, colorless. transparent glass which after being made into fragile pieces were art objects in the finest palaces.

Glass, rather than a raw material, was treated as transparent silver.  The use of glass for windows was a slow, gradual change.  Glass was very expensive and flat glass was difficult to make. Only very small windows were made and for the wealthy.  In the Middle Ages, windows began to show beauty - the stained-glass windows of England and France's cathedrals, although with limitations, showed the power of the glass makers of that time.

Today in Pioneer History: "On December 12, 1980, a notebook belonging to Leonardo Di Vinci was purchased for $5.1 million by American oil tycoon Armand Hammer at auction.  The manuscript written around 1508, contained 72 pages with 300 notes and drawing relating to water and how it moved.  After Hammer's death and an museum visit, the codex was sold to Bill Gates for an estimated $30.8 million.  Gates loans the codex to museums for public display.  (what else would do with it???)
