I mentioned in my previous post that David Roberts kindly let us bring some pieces to raku fire during our SPA weekend at Kindrogan. I’ve done naked raku once before, at Gray’s School of Art, and I’ve been meaning to have another go. This experience has inspired me to try and do further firings at home, perhaps over the summer.
David is a master of raku ceramics. His large-scale pieces are breathtaking and it was fascinating to discover more about his process. He cleverly juxtaposes rough and smooth surfaces in his pieces which adds depth to his already complex designs.

We were asked to bring some already bisque fired pieces to the workshop. Ideally these would be burnished to a smooth finish or have terra sigillata applied. The pieces were dipped into a barrier slip, some with areas already masked off. Once dry they were dipped into a raku glaze and dried again. At this point they could be fired as they were, or designs could be incised through the layers of glaze and slip. The slip is what stops the glaze from adhering to the pot during firing. The areas that have been left bare will become black during reduction.
