Raku fired bowl

Experiment

The ceramic raku firing technique (description below) offers great colour variations with the use of copper oxide in the glaze. Depending on the amount of oxygen allowed onto the object during the firing process, the result is variations from vivid metallic copper colour to turquoise hues.

Process & Production

The Raku technique is essentially when glazed ceramics are taken from the kiln while they are still glowing red hot and are then placed in a material that would be able to catch fire, such as sawdust or newspaper. This technique is used to starve the piece of oxygen, which creates a myriad of colours within the glaze. Raku firing without glaze on them means that the oxygen is taken from the clay itself rather than a glaze, which results in some areas having a matte black coloring. https://www.soulceramics.com/pages/raku-firing
