Oceanside Compatible & System 96 Reactive Opal Art #700-96SF.
This System 96 glass goes into the kiln clear and comes out with cool colorful swirls of colour - including Pink and Burgundy! The magic happens because Clear Tin has been stirred onto a Clear Base creating subtle Clear-on Clear swirls that look similar to the Clear Baroque. When placing topside down against a Copper-bearing glass and fired, the areas of Tin change color in the stirred pattern revealing OpalArt style swirls. Some soft wisps of White are also common to see in areas where the Tin lies deeper in the Clear Base.
