This triple dip WonderTubing consistent of one layer of NS-34 Extra Light Yellow over two layers of Exp. #113 Lucid. Both flame and color stable, this tubing can be worked in any type of flame. For best results, we recommend using an sharp and oxidizing flame to work the prep until it is translucent, then allowing the Ex. Light Yellow to be kiln struck. Kiln striking this color for longer periods of time will bring out more fumey yellows on the surface.
