- Working Notes
-
A speckled glass made by Double Helix. The glass is COE 104
Ossa is the first in our new speckled color family. Based on the popular “speckled luster” test batches OP-434 and OP-507. Ossa is a rich purple lustering glass with thousands of refractive inclusions dispersed throughout each rod. When exposed on the surface, Ossa can be left as a purple speckled glass, or it can be reduced to develop a variety of luster effects. Using variations in flame chemistry, Ossa can produce a solid silver metallic layer, or a multicolored iridescence. When reduced and encased, the inclusions in Ossa produce a textured mother-of-pearl effect reminiscent of some dichroic coatings.
All tested compatible with Effetre Clear 104 coe.

Speckled colours are reduction glasses with thousands of refractive inclusions dispersed throughout each rod. Reduction glasses contain silver that; when properly heated, cooled and touched by a reducing flame, will come to the surface of the glass to create a thin layer of silver.
