Stem cup with yellow glaze
This stem cup demonstrates an attractive use of a monochrome yellow glaze at Jingdezhen. This colour glaze was used to decorate court porcelain for some five hundred years of the imperial era in China from AD 1403 to AD 1911. Potters fired the stem cup twice, first at a porcelain temperature of around 1280 to1320 °C and then in a second, lower-temperature firing to vitrify the lead-fluxed, iron-pigmented glaze. The foot has a six-character underglaze blue reign mark of the Jiajing period.

Reason for treatment
Remove remnats of old fills and re-fill chips. Remove staining from cracks.
There are two cracks (approximated 4-5 cm) extending down from the rim and exhibiting dark brownish staining. There are approximately nine small chips to the rim. The surface exhibits extensive wear and various scratches, especially on the interior. The interior has and overall cloudy appearance and under UV light fluoresces a greenish color. There is likely a resinous or waxy material applied to the interior as part of a previous restoration.
The resinous/ waxy material on the interior of the cup was found to be soluble in a 1:1 solution of Industrial methylated spirits (ethanol,methanol), deionized water. This was used to reduce the material and applied using cotton wool on a wooden skewer. The stains in the cracks were reduced using Ariel automatic (anionic and non ionic synthetic surfactants,sodium tripolyphosphate) applied on cotton wool. Color fills were created to fill the chips in the rim using Fynebond epoxy, bulked with Cab-o-sil (fumed silica) and toned with dry pigments. The fills were sanded smooth using Micromesh abrasive cloths.
