This is one of my favorite translucent WYSIWYG colors.  Beryl is fascinating to me in the same way the Paris Greens are because of the similarities to bottle glass colors.  This brownish olive green transparent is wonderful for solid color sculpting and works very nicely for blown work as well.  For larger blown work, I recommend sandwiching between a clear tube and another layer of clear or transparent color, reason being that Beryl is made up of a significant amount of copper.  When a heavy copper color is not encased and on the surface for blown work that will be melted, blown, and manipulated it will tend to react with different amounts of propane and oxygen in your flame mix.  So where Beryl may feel similar to working a Paris Green, or even clear, it will prefer working about halfway to three quarters of the flame length away from the tip of your torch in an even mix of gas. Heavy reduction or propane in the flame mix, very close to the tip of your torch, will react with the copper in the color causing different surface effects. 

A very natural tone for your color palette, Beryl will compliment many other Glass Alchemy colors and when standing alone should be given the opportunity for light to transmit through the color for best presentation.
