In recent decades, several new methods for studying archaeological artifacts, mostly based on digital technologies, have been developed. One of the most promising trends is 3D modeling, allowing researchers to deal with an exact virtual copy of the artifact, which can be manipulated in every way. We propose a new method for determining whether non-applicable fragments belong to one artifact, based on 3D modeling and mathematical statistics. After applying it to two (and possibly more) fragments, one gets an unambiguous answer as to whether the application is statistically reliable (i.e., falls within 95 % confidence limits). Precise computerized measurements on 3D models, following a single algorithm, allow us to verify the results. This method was tested on non-refitting fragments of figurines from the Bronze Age cemetery Tourist-2. Two anthropomorphic figurines from the same cemetery were used to verify the conclusions and elaborate the algorithm.
