The Moon Jar is based on the Korean storage jar and thrown on the wheel using Raku clay which helps with the thermal shock of the Raku firing. The Moon jar is then turned to refine the shape and a foot ring turned into the bottom. The neck rim and the foot ring are then brushed with terra sigillata, a very fine slip, and polished to a soft shine.
The Moon Jar is decorated using the Naked Raku technic. A resist slip, and then a sacrificial glaze, are then applied to the body of the Moon Jar. During the firing the moon jar is taken from the kiln, red hot, and placed into a sawdust bin. The thermal shock makes the sacrificial glaze crack and smoke gets into the cracks and onto the body of the pot. The Moon Jar is then taken form the sawdust and plunged into water where upon the sacrificial glaze pops off the body of the pot like an egg shell revealing the crackle patten from the smoke.
The rim and the foot ring turn black in the firing from smoke but the body has the black and white crackle pattern and soft shine of the burnished body. Both the body, rim and foot ring are polished to enhance the soft shine of the burnishing and terra sigillata.
