For reduction, work in a neutral flame, cool, then reduce.  For kiln striking test a rod in your annealer.


Nyx was one of our earliest colors and was made from Effetre Clear.  Nyx will reduce  to a mirror like or multi colored luster and kiln strikes through a steady fade from black to light blue.  You can determine the coloration through annealing time, temperature and placement in your kiln.

Tips:  We recommend kiln striking a rod of Nyx to estimate the kiln striking time at your annealing temperature.  Our kiln striking tests were perfomed between 950 and 970 degrees F.  One hour annealing time produced a dark blue, while light blue tones developed after three to four hours.  Higher annealing temperatures result in more green colors.  Encasing may alter kiln struck color.  For reduction, work in a neutral flame, cool, then reduce.
