The use of carbon-14 dating to detect art forgery is rare primarily because the process requires the destruction of large quantities of material from the object being tested.1

While carbon-14 dating is a highly effective method for determining the age of organic materials—by measuring the decay of radiocarbon after an organism dies—it is often impractical for art conservation and authentication. Because art objects are typically unique and valuable, the necessity of removing and destroying a significant sample size makes this technique unsuitable for most forensic examinations in the art world. Instead, experts rely on a combination of stylistic analysis and other technical methods, such as microscopic examination, chemical analysis of pigments, and X-ray imaging, which can often be performed with minimal or no damage to the piece.12
