Experimentally produced objects for the purpose of the TEMPA 3D project. Experiments were held in January and November 2024, and included engraving of soapstone from Rennesøy and Målslev and sandstone from Kamyana Mohyla. Experimentally produced objects were specifically designed to look at the technological traces of the surface modification processes via image-based 3D modeling.
Dataset includes 23 models of the experimentally produced objects. Among other this includes flint and quartz marks on soapstone, sandstone, bone, and antler as well as experimental replicas of Kamyana Mohyla churinga and soapstone line sinkers. For most engravings the modification time was recorded along with the production tool. The accuracy of the models in the dataset are around 0.1 mm, the resolution — around 0.03 mm.

EPO2.11
A flat piece of the Rennesøy soapstone. Grinded on a sandstone slab. Engraved with the quartz blade, the sharpest in the collection, the flint blade, and the flint microblade. Only one pass per engraving was made (sawing) to compare traces of less intrusive and effort-cost engravings.

Comments on the slices analysis
Engraved with a flint blade, a short straight edge. 1 pass per line. Soapstone appeared to be harder in this part of its surface, which made the engraving process harder
