A spectacular metallic, iridescent glaze that produces a myriad of colors including: maroon, gold silver, blue, red and copper. Best when applied medium to thick.
Observations by Cindy Bracker when using this glaze:
"I was blown away by the deep blue-greens blending into yellows, and subtle golden metallics that edge toward magenta & purple when reduced in Excelsior. With leaves as the reduction material, dark greens edging toward silvery-metallic was predominant, while the sawdust provided more of the results I expected – flashy copper metallic with the deep purple and blue iridescent tones. Laguna’s R-13 Copper has earned itself a spot in my regular repertoire of Raku glazes."
