Nesshenge, a Neolithic replica in Ness Botanic Gardens, was meticulously crafted 15 years ago. How has this archaeological experiment, showcasing ancient
Archaeological ostrich eggshell (OES) bead assemblages manifest in a variety of colours that result from exposure to high temperatures. It is unclear, however, whether this colouration is taphonomic, through post-depositional heat exposure, or the consequence of intentional heat treatment of OES to produce a desired colour (or for some related purpose). In this study, we investigate the latter question using controlled and actualistic heating techniques to determine (1) if OES beads remain usable following exposure to high temperatures and (2) whether abrasive wear that occurs prior to heat treatment can be distinguished from wear that occurs after heat exposure. Twelve sets of 20 OES beads were manufactured and subject to one of two investigative tracks. Track 1 simulated abrasive wear using a rock tumbler before heat treatment in either a muffle furnace or wood-burning fire. Track 2 beads were heat treated prior to abrasion. The results demonstrate that indirect exposure to a wood-bu
