Each naked raku piece is carefully hand burnished to create a beautifully smooth, polished surface before being finished with layers of terra sigillata — a refined liquid clay made from ultra-fine particles that produces a soft natural sheen without the use of glaze.

A feather is being applied to a pot that has been heated to 700 degrees celsius. You can see that the carbon released from the feather is instantly trapped into the clay body.

Here is an example of a effect that I have nicknamed 'Ghost Feathers'. Each feather is applied to the heated pot at precisely the right moment to create a contrasting design. The lighter feather on the left is placed on the pot at it's hottest point, and the feather on the right is placed when the pot is 100 degrees cooler. This ying and yang decoration has taken many years to perfect.
The Great Pottery Throw Down
Three of my raku pots were proudly featured on series 8, episode 4 of The Great Pottery Throw Down, where they were showcased as inspirational reference pieces for the contestants’ challenge. The show carefully selects work from respected ceramic artists who specialise in particular techniques, making it an incredible honour to have my raku pottery chosen to represent this exciting and unpredictable firing process on national television.
