GROUND-FREEZING ON ARCHAEOLOGICAL EXCAVATIONS: LIFTING A MEDIEVAL CHALICE FROM ST GILES HOSPITAL, BROUGH.
Author(s): P Clogg, J Jones
The paper examines the feasibility of using ground-freezing as a technique for lifting artefacts from archaeological excavations, and its advantages over other lifting techniques. The different ground-freezing techniques are discussed, and the chosen technique (using solid CO2) is described in detail. The second part of the paper documents the use of ground-freezing in the field, to lift a Medieval mortuary chalice.
