Before I could consider the foregoing processes in various aspects of prehistoric Georgia culture I first had to determine what changes, if any, took place, and in what categories. Also, I had to decide, when it was possible to do' so, to which of my categories of cultural traits each ceramic feature belonged. For example, is fabricmarking a decoration or is it simply a technical product, resulting from wrapping a vessel in a fabric before it was wholly dry? Was surface color of unpainted vessels deliberately controlled by the ancient Indian potters, and thus an aesthetic trait, or were only technical manufacturing motives and accidents of firing involved?
