# A collaborative exhibition, Artefacts, showcasing works by Lothar Böttcher and Caitlin Greenberg, will officially open at the Pretoria Art Museum on Saturday. Both artists, who are renowned for their passion and specialised use of glass in their art, are alumni of the Tshwane University of Technology. The university says Böttcher and Greenberg examine inner voices, personal dilemmas and philosophies in this exhibition, inviting visitors to experience the space through a fourth dimension, one shaped by memory, emotion and embodied presence.
