How to Reduce Keto Double Helix Glass:

• Work in a neutral flame
• Cool until glow is gone
• Create a reduction flame by reducing oxygen, increasing propane
• Gently reheat in reduction flame

Speckled colours are reduction glasses with thousands of refractive inclusions dispersed throughout each rod. Reduction glasses contain silver that; when properly heated, cooled and touched by a reducing flame, will come to the surface of the glass to create a thin layer of silver.
