Skiron is the new, sliver-striking, rainbow glass.  A major improvement over Luna 3 and Khaos, it resists over striking to khaki.  Skiron works best when reset, cooled, and struck. Cooling and striking times will vary based on bead size, flame temperature, and other factors but general guidelines are;

Surface applications: reset, cool for 30 seconds, strike for 30-45 seconds.

 Encased applications: encase, reset, cool for 45 seconds, strike for 45-60 seconds.

The cooling cycle is an important factor in repeatable end results. Shorter than recommended cooling times typically yield white and purple, while longer cooling times can yield dark Amber with blue tints. Somewhere in between lies the ideal cooling/striking timing for your application and set up.
