Northstar Amber Purple (13) - Knuckle Tube End

Knuckles are a small section of tubing with a tapered and crimped clear end. Diameter, length and wall thickness vary.

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 amber, 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.
