Louis Comfort Tiffany Favrile glass remains one of the most copied and misrepresented categories in American decorative arts. Artificial iridescence, incorrect signatures, altered pontil marks, and polished rims routinely distort authenticity and collector value.
This system replaces surface-level visual attraction with a structured authentication and ownership framework specific to genuine Favrile production.
It begins with iridescence behavior, surface sheen characteristics, and internal color striations that distinguish authentic Favrile glass from later reproductions. It then analyzes L.C.T. signatures, pontil marks, acid-etched stamps, and signature placement variations across production periods.
The form analysis guide explains mold-blown versus free-blown techniques and how construction methods reveal authenticity and era. The condition risk section evaluates polishing, rim grinding, and restoration interventions that materially impact value, even when visually subtle.
The master guide integrates authentication methodology, construction analysis, condition assessment, appraisal positioning, resale strategy, and long-term ownership planning.
This framework should be used before acquisition, auction submission, insurance scheduling, resale listing, or restoration decisions.
