DJR Expert Guide Series, Vol. 105 — How to Identify Recast & Re-Marked Antiques (Blacklight & Chemical Testing Method)
Recast antiques, forged hallmarks, and artificially aged surfaces are some of the most common—and most deceptive—problems in the antiques world. Modern reproductions often mimic the general shape and style of genuine objects, but subtle differences in patina, tool marks, construction, and surface chemistry expose them instantly to a trained evaluator. Most collectors and resellers never learn these professional techniques, leaving them vulnerable to expensive mistakes.
DJR Expert Guide Series, Vol. 105 — How to Identify Recast & Re-Marked Antiques (Blacklight & Chemical Testing Method) teaches you the exact hands-on techniques used by appraisers, dealers, and conservators to detect recasting, forged hallmarks, artificial patina, modern repairs, and chemical aging. Using UV blacklight, safe chemical spot tests, and construction analysis, this guide gives you a complete system for authenticating metalwork, ceramics, wood, textiles, and early materials.
Inside, you’ll learn how experts:
Use blacklight (UV) to identify modern glues, paints, varnish, resin fills, and overpainting
Detect repairs, replaced components, and restoration on ceramics, metal, wood, textiles, and paper
Perform safe chemical spot tests (vinegar, acetone, ammonia fumes, warm-soap bronze testing) to expose artificial aging
Recognize mold seams, grinding marks, surface pitting, and weight differences in recast bronze and brass
Identify forged hallmarks using font analysis, impression depth, tool-mark consistency, and placement accuracy
Separate natural patina from modern chemical treatments by evaluating color variation, oxidation behavior, fluorescence, smell, and texture
Understand common red-flag scams: barn-find fakes, artificially darkened pieces, incorrect signature placement, and perfectly identical copies
Evaluate metal, ceramic, and wood surfaces correctly by analyzing oxidation, wear patterns, and manufacturing traits
Apply a professional-level inspection process that prevents costly purchases and improves authentication accuracy
Volume 105 gives collectors, resellers, estate buyers, antique dealers, and new appraisers a clear, repeatable, professional-level system for detecting recast and re-marked antiques—using the same methods trusted by authentication specialists.
