Cherry

Cherry is the most eye-catching member of the intense opaque family. It is a bright candy apple red that is well suited for stringer application and blown work. Cherry is slightly sensitive to reduction, so work in a soft neutral flame. Cherry is, however, heat sensitive, so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the color, but not necessary. Cherry can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. A nice color effect to try is a layer of Rootbeer over Cherry. 

Available in Rod, Frit, Fine Frit, Powder Frit & Tube. Cadmium tubes are unencased.
