The Judges III is a sculptural assemblage featuring materials ranging from biomedical data and geological field-research to watercolour techniques and artisanal sculptures. Within the installation, minerals unfold as paint, as slip, as clay and as glaze and piles of mineral sand occur, which were funnelled and poured, flowing between objects.

The key image that informs the work is a set of massive brooding stone outcrops suggesting the character of judges. Through this work Mackie explores the concept of judgement and its role in all our lives. A powerful controlling force whether one is the judge or the judged.
