In the studio a Collagraph matrix/plate was used to lightly impress into clay, tools were then used to draw into this and also to apply extra marks. After a few days the plaque was completely dry. To enhance the impressions and marks charcoal ink was painted on and carefully rubbed well into the deep impressions. Once dry, the excess charcoal powder was removed from the surface and then the plaque was sealed with a varnish.
