Double Helix Skylla
Based on the popular test batch TK-645 and a relative of Terranova 2.1, Skylla is a silver striking and copper ruby glass. The silver strike produces bright blues, purples and teals while the copper ruby produces reds when applied in thin layers all the way to black if thickly applied. Skylla has several improvements over previous silver/copper striking colors. The colors are brighter, the reset is complete, the geneous and the copper ruby is redder.
