Io Star - Trautman
Pronounced EYE-oh, this reactive sparkler is named for one of the moons of Jupiter (and for Joe Jeffrey's Io Glass, in honor of his polite persistence in pleading for this exact color.) Io Star resembles Heavy Blue Stardust in the rod, because it has more of the aventurine sparkle than the Shooting Star. But it also has more silver, and is more reactive than the Shooting Star -- and this gives it a beautiful rich green sparkle base color.
Like Shooting Star, Io Star will flame strike, and will strike a bit more in the kiln during a regular 1050° F anneal cycle. The glittery component in this glass is based on the Blue Stardust technology, so it's quite stable -- but we recommend AVOIDING high temperature kiln cycles that some people like to use for kiln-striking an amber/purple, due to the aventurine.
Please don't run this color over 1050° F in the kiln; safe in implosions.
