Celadon<\/h1>\n

Between history and studio experience.<\/p>\n

\n

The Depth of a Colour<\/h2>\n

From soft greens to deep blues, celadon reveals a long history of ceramic experimentation. From Chinese traditions to my own studio practice, its colours and surfaces invite us to observe the relationships between matter, fire and time.<\/p>\n

Its appearance emerges through the interplay of composition, surface and firing conditions.<\/p>\n<\/div>\n<\/div>\n

01 \u00b7 History and Tradition<\/p>\n

A Colour Across Traditions<\/h2>\n

Originating in China, celadon spread across different ceramic traditions in Asia. Its tones, often associated with jade, bring colour, form and surface into a close relationship.<\/p>\n

In Japan, this tradition took on other interpretations. The articles gathered here explore its reception and the relationships between glaze composition, application and firing.<\/p>\n

The yunomi shown alongside is a piece from my studio: a contemporary engagement with the tradition of tea vessels.<\/p>\n

02 \u00b7 My Experience with Celadon<\/p>\n

Where Glaze Meets
the Clay Body<\/h2>\n

During my first firing in a gas kiln, tests monitored using cone 6 produced different results on porcelain and terracotta.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>

On Porcelain<\/h3>\n

The celadon produced a good result. The glaze's transparency enhanced the low-relief designs; applying a thicker layer remained a possibility for the next test.<\/p>\n<\/div>\n

\n

On Terracotta<\/h3>\n

The colour turned dark grey. I considered the possibility of an interaction with iron in the clay body \u2014 a hypothesis arising from that particular experiment, rather than a general conclusion about all celadon glazes.<\/p>\n<\/div>\n

Glaze composition, layer thickness, clay body and firing conditions need to be considered together. A pyrometric cone indicates the combined effects of time and temperature.<\/p>\n
