Amber/Purple

Of the striking colors in the borosilicate palette the Amber/purples are some of the most exciting. Amber/Purple is the first in a series of five Amber/Purple colors. It is well suited for sculpture and moderately thin blown work. The color can produce pale yellows to ambers to a deep purple. To yield the most vibrant purples, work in a hot neutral to slightly oxidizing flame. Reduction will affect the strike. Try encasing your favorite Amber/Purple with Violet or Lavender. To enhance Amber/Purple try backing it with Star White.

Available in Rod, Frit, & Hand-pulled tube.
