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.
