Did you know that Bohemia was once part of the country of Czechoslovakia? It now resides in the Czech Republic? The area has been producing glass since the 13th century.
The glass makers in this region quickly discovered that if you mix potash with chalk it produces a clear glass that was more stable than the glass that was coming out of Italy.
When collecting or selling Bohemian glass, you need to keep a watchful eye on the quality of the piece. The glassware is still being made today by quite a few companies. Even in the Bohemia area, you will find lesser quality pieces that have been brought in from China and other locations.
