Abstract
The lost wax or investment casting process used extensively in gold jewellery fabrication is subject to the effects of a large number of process variables. One consequence of this is that where problems arise or exist in its application, they can be difficult to understand and solve. In order to promote optimization of the process the authors have studied the effects of a number of process variables. In this, which is the second in a series of articles describing their findings, the authors describe, first, the methods they have used and secondly, the results of observations made of the gas pressures in moulds during casting and the effects of variations in these pressures upon the quality of the casting produced.
