Back in Novy Bor he focused on painting glass and devoted his time to experimenting with new decorating techniques.

He invented Lithyalin glass that has a marble look. Material was already known but Egermann worked the surface in a way that they looked like precious stones. The stones became very popular and Egermann and imitators exported their products through the hole of Europe. His invention of the Lithalyin glass stones was the first impulse with which Friedrich Egermann changed the glass industry in Bohemia and the rest of the world. In 1832 was his biggest invention: the red glaze. Red was always a popular color for glass and until then the glass makers only knew how to make a nice ruby red with the help of the expensive ingredient gold. Egermann found a way to make a nice ruby red glaze with just copper ions. THESE ARE ANTIQUES NEVER USED JUST DISPLAYED
