Craquelure—the natural network of cracks formed in aged paint and varnish layers—is one of the most misused “age indicators” by art forgers. While genuine craquelure develops slowly over decades or centuries, artificial craquelure can be created in minutes using heat, solvents, crackle mediums, or mechanical stress. Correctly interpreting crack patterns, varnish behavior, and layer interaction is essential for spotting forged or artificially aged paintings.
DJR Expert Guide Series, Vol. 230 — Master Guide to Detecting Artificial Craquelure and Varnish Aging provides collectors, appraisers, and conservators with a full forensic framework for distinguishing authentic aging from modern fabrication. This guide explains how natural craquelure forms, how paint layers deform over time, how different supports move, and how artificial cracking methods leave detectable clues under raking light, UV, and magnification.
Inside, you’ll learn how experts:
Identify natural vs artificial craquelure based on pattern, depth, and irregularity
Recognize heat-induced cracking, surface-only cracks, and uniform crack networks
Detect chemical crackle mediums, shrinkage patterns, and gloss inconsistencies
Evaluate mechanical cracking, repetitive tool marks, and crushed pigment edges
Distinguish canvas vs panel craquelure based on support movement and stress direction
Analyze varnish oxidation, resin aging, micro-bubbling, and true UV fluorescence
Identify artificial patinas, synthetic yellowing, and wiped-on grime
Use microscopy to examine crack-edge morphology, pigment displacement, and layer penetration
Interpret environmental aging factors such as oxidation, shrinkage, and complex crack interlocks
Determine when professional lab testing, conservation review, or formal authentication is required
Volume 230 gives collectors a complete, museum-grade system for evaluating craquelure, varnish aging, and paint-surface behavior—exposing artificially aged surfaces and protecting buyers from fraudulent “antique” paintings.
