NS-15 Turquesa is a more saturated version of NS-14 Irrid and produces similar effects. When worked in an oxidizing flame Turquesa yields more pronounced metallic blues. When reduced, deep sea greens result. Because it is more saturated than Irrid, Turquesa can be used for thinner blown work without thinning out. Try layering it over an opaque to yield new effects. Also try reducing Turquesa, then encasing with clear. For additional information refer to Northstar Newsletter issue 4.
