Magnesia glaze on the inside with 3% iron as a colorant. This cup was once fired in a wood/salt atmosphere to cone 10. Cup was hand built over a wood hump mold with texture added to the outside by pressing and paddling with hand made and found wooden sticks.

Wood/Salt fired cup with woodash celadon glaze in the Chinese Longuan celadon tradition.

Trans Clear Pumice Glaze that can be found on Glazy.org This glaze is high in Calcium Carbonate and goes clear green where thick in reduction atmospheres over 1260 degrees cooled quickly. In an oxidized atmosphere this glaze goes clear/yellow. This cup is clear/yellow on the inside and clear/green on the outside indicating 2 different atmospheres at different times in teh firing.

VC Matte base. This cup has crystals from dark brown to green. The clay body looks reduced, but the interior of the cup looks oxidized and is a buttery yellow. My guess is the outside is showing carbon trapping from early in the firing producing the dark brown color. The green color may be coming from the salt in the kiln, but more tests are necessary.

Fake Ash glaze is darker and more brown on the exterior. Interior is showing more rivulets with more yellow coloration. Glaze has over 40% calcium carbonate, but has not run much. So, very possible the temp was not at cone 10. Surface is dry, but mature.

This is one of many tests for a blue celadon. It is showing a blue/green cast, but glaze needs to be much thicker. Glaze analysis was pulled from Nigel Wood’s book Chinese Glazes. Next firing will be same unaltered glaze with thicker application. Slight crystallization is evident.
