We have not seen this color in years but I recently found a box with out of production TAG in it manfuactured in 2009. These rods are labeled "seconds" but they look like firsts to me. The cold rods are green. Photo from Jenny is golden Emerald and Taxco Silver.
Working notes from TAG:
GOLDEN EMERALD: (TAG-104-11) This is a pale green transparent reducing glass, similar to our Taxco. Golden Emerald’s effects also differ over a light or dark base glass, and by how much oxygen you use in your reduction flame. When reduced with little or no oxygen, by itself, the Golden Emerald takes on a golden metallic sheen over its transparent golden green. When reduced with some oxygen, on a dark base glass, Golden Emerald produces strong metallic oil-spot colors of purple, blue, electric green, and more. It is difficult to encase the reduction on Taxco and Golden Emerald.
