Precision drawings made fast with lasers

Peter Demján

Understanding the development of pottery shapes and forms plays an important role in reconstructing ancient living and making. Each fragment has to be carefully studied and precisely documented, including a drawing reconstruction of the original vessel based on the profile and estimated diameter. This process is usually quite time-consuming and involves either drawing by hand or creating a digital drawing based on a 3D scan.

During this season of the Kaymakçı Archaeological Project, the pottery processing team got new reinforcement in the form of a prototype Laser Aided Profiler (LAP), developed specifically for measuring the profiles and circumferences of pottery fragments.

The Profiler enables us to produce a high-quality digital drawing of a ceramic vessel based on a fragment in a matter of minutes. Such drawings can then be used to analyze various vessel types in traditional ways or to compare the shapes of profiles digitally and calculate their similarity. This process, called morphometrics, enables us to analyze thousands of fragments from different parts of the site, or even different sites, without having to go over every single one by hand.

Look forward to more posts from Gygaia Projects over the course of the year!
