Add Iridized Pattern to Your Colored Glass

Bullseye produces three clear -on-clear collage glasses with iridized surfaces, which can be layered onto any of Bullseye's colored glass to add iridescent surface patterns.  Simply place a piece of clear-onclear colage glass with the iride side face down on the kiln shelf.  Then cap it with  a 3mm piece of colored glass.  After a full firing, the texture will be flat, but the irid pattern will remain.  


When firing the irid side of a glass against the kiln shelf, coat the shelf with primer instead of using ThinFire paper, which can cause pitting on some irid coatings.
