Northstar's Dark Amethyst boro is a light transparent violet color. This is a “what you see is what you get” color. Use in a slightly neutral to oxidizing flame for best results. NS-106 Dark Amethyst works like butter so do not hesitate to spread it over other colors. The color looks best in solid color blowouts and sculpture work. Stringers tend to lose color and may appear as a clear Violet.
