To make the glass of Venice go over a high reputation, it goes without saying that this technology is a secret. In 1688, a method of casting glass was invented. This brought glass and glass windowpanes of becoming much more common material. The glass press machine was invented in 1827, making mass production of relatively inexpensive glass products easy. Glass pioneer, William J. Blenko, as the first glass producer in the US, was confirmed to use the cylinder method to create flat glass by the 1920's
The freewheeling country of Czech and Slovakia is still known today as two of the world's best cut glass and cut quartz producers. Elegant anniversary and birthday gift with prizes as a work of cut crystal.
