Arke 2 is our updated formula that increased the silver and improved rod quality.  Arke 2 is a transparent cobalt luster color that develops a variety of exterior metallic finishes and holds it’s luster under a clear encasement.  It’s the lightest of our three cobalt silver glasses; Arke 2, Triton and Iris.  

Variations in flame chemistry, exposure time and temperature alter the color of the exterior luster.
