NS-136 Purple Lilac is a beautiful new color from Northstar Glassworks. The color is a nice purple/pink when used. The color rod before used looks opaque but after used it can yield many shades ranging from opaque to very nice transparent color. Northstar recommends using this color in any type of flame. For a more opaque color use a slightly reducing flame and for beautiful transparent color use an oxidizing flame. This color can be used in any application without problems as well. This is considered to be a striking color so the more you anneal it the more opaque it will turn. Please remember that if you thin out the color too much you will not be able to bring it back to a nice opaque color.
