Large wheel-thrown work
Tessha-glazed Porcelain Bowl
21 of these burgundy, wheel-thrown bowls, were commissioned by Queensland’s Premier’s
department in December 2006 to be given as gifts by the department.
The bowls now feature in the Corporate Catalogue of Artisan Gallery, Brisbane.
Each bowl, individually handcrafted from porcelain, was
fired to 1280 degrees centigrade in reduction. They are finished with a feldspathic glaze
and the sparkling crystalline surface is the result of a slow cooling, which causes
visible ’spangles’ of haematite to form from an iron-rich glaze. The overlaid glaze is
a traditional chun glaze appearing black where thin and blue where it is thicker.
The glaze is applied in a spontaneous manner conferring individuality to each piece.

The overlaid glaze is a traditional chun glaze; a small proportion of red iron oxide creates the blue colour, which is an optical effect caused by the refraction of light through tiny bubbles in the glaze.
