Work in a neutral flame. Cool until the glass is no longer glowing. Expose the glass to a reduction flame, whole keeping it from getting hot. Brief (5-10 seconds) and repeated exposures produces the best results. For the satin textured luster, work in the tip of a larger reduction flame, let cool and then briefly reduce again until a subtle texture begins to form.
See our How To section for more detailed working information and tips on using our reduction colors.
