Blue Caramel

Blue Caramel is a lush high intensity silvery striking color. If worked in a super oxidizing flame it will yield smoky blues and greens. If reduced it provides the user with an extremely silvery tan color. If encased, the color turns to be a brilliant metallic green. It is easy to work and is well suited for stringer applications and blown work. Try layering Sublime over the surface for a wonderful green effect!

Available in Rod, Frit, Fine Frit, & Powder.
