Finally, the face is "fleshed," meaning clay is added until the tissue thickness markers are covered, and any specific characterization is added (for example, hair, wrinkles in the skin, noted racial traits, glasses, etc.). The skull of Mozart was the basis of his facial reconstruction from anthropological data.
Polymer clay is a type of hardenable modeling clay based on the polymer polyvinyl chloride (PVC). It typically contains no clay minerals, but like mineral clay a liquid is added to dry particles until it achieves gel-like working properties.
Now, there is also computerized 3D forensic facial reconstruction. Manual model clay techniques are used within this method, but the computer systems vary, in that some computerized systems used 3D animation software to model the face onto the skull, while other systems use a virtual sculpture system with Haptic feedback.

The team scanned and 3D-printed the rebuilt skull, which formed the basis of a reconstructed head created by Dutch paleoartists Adrie and Alfons Kennis, twin brothers who built up layers of ...
Polymer clay is a modelling material that cures when heated from 129 to 135 °C (265 to 275 °F) for 15 minutes per 6 millimetres (1 ⁄ 4 in) of thickness, and does not significantly shrink or change shape during the process. Despite being called "clay", it generally contains no clay minerals.
Once molded, and clay removed, new mold cleaned out, the positive is one part of the mold and the new mold is the other side which has the negative of the newly sculpted prosthetic. This gives two or more pieces of a mold - a positive of the face or body part, and one (or more for complex molds) "negative" mold pieces with prosthetic sculpted in.
