How do art forgers operate?
<|assistant|>
Art forgers will sometimes use existing artworks as their basis for a new creation. They may make minor alterations to a work, such as changing the date or location of a painting, to make it appear authentic. Forgers also sometimes create an entirely new work by blending various artworks, photos, and media together into an acceptable composition. These works can then be sold as original pieces with false titles and biographies. 

For forged sculptures and artifacts, forgers will use molds made from original works or from photographs of existing works, which will produce exact replicas. The pieces can then be glazed, colored, and distressed to make them appear authentic and older. Other techniques forging artists may use includes overpainting, the application of patinas, or the alteration of documents to justify the artwork’s age or origin.
