The Fenton term "Favrene" was coined by combining parts of Tiffany's "Favrile" and Carder/Steuben's "Aurene."
The key to creating the particularly vivid iridescent effect of Favrene is more than just cooling and reheating, as it involves a controlled temperature environment in the glory hole.
Was the vase pictured above sold to you as Fenton???
