Shifting techniques in perforating animal teeth and metal objects. Some examples from Early Bronze Age contexts

This paper addresses shifting techniques between manufacturing two types of raw materials. On the one hand, they are copper-based alloys that were processed in the Early Bronze Age (c. 2300-1600 BCE) only by a few craftspersons, and, on the other hand, well-known and commonly processed animal hard tissues. At least one technique we observed on the metal objects originates from those of working with animal hard tissues, while the other one can be found in already published evidence. Application of techniques known from bone and antler processing in metallurgy indicates cross-craft communication and learning processes.
