Soda-lime glassrod produced by Double Helix, Aurae is a light purple, silver-reduction glass. Variations in the reduction process create mirrored, iridescent or satin textured lusters. If encased, the luster results in a pearlescent effect.

Working tip Work in a neutral flame. Cool until the glass is no longer glowing. Expose the glass to a reduction flame, while 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.
