Bowl with copper-red glaze
‘Sacrificial’, fresh or deep red monochrome-glazed porcelain of the Yongle and Xuande era represents the peak of technical achievement at Jingdezhen. As vessels ordered for ritual use by the early fifteenth century Ming emperors, they enjoy a status above that of other porcelains. The skills used to create these extraordinary red glazes were lost in China from the mid-fifteenth century until they were rediscovered in the late seventeenth and early eighteenth centuries. The glaze has ‘crept’ at the rim of the bowl to reveal the pure whiteness of the porcelain body. This Yongle example has incised stylised lotus lappets around the foot ring. The glassy glaze is covered in tiny pin prick holes like skin pores and the colour possesses an incredible powdery depth, yielding layer upon layer of strong red shades of colour.

Clean. Consolidate moving crack
Surface dirt. Running crack from rim with movement and staining. Two additional small running cracks with staining
Cleaned with distilled water and a few drops of Synperonic N (non ionic detergent, nonylphenol ethylene oxide condensate), using cotton wool swabs. After cleaning, surface rinsed with distilled water on cotton wool. Surface wiped with a dry absorbant tissue to remove any remaining distilled water. All cracks were steam cleaned to remove dirt.Ariel automatic (anionic and non ionic synthetic surfactants,sodium tripolyphosphate)on cotton wool strips were applied locally over the cracks on the interior surface and covered with Clingfilm. After leaving overnight the Clingfilm was removed and the cracks steam cleaned to remove dirt and residues. This process was repeated. Following a further steam clean, dirt had been successfuly removed from the smaller cracks however dirt remained within the large running crack. Laponite RD (sodium magnesium lithium silicate) was mixed to a gel with distilled water and applied as a poultice to the crack on the exterior surface. Strips of Japanese tissue were used as a barrier layer. After leaving overnight the Laponite was removed and the cracks steam cleaned once more. The dirt had now been successfully removed from all cracks. To ensure no significant residues remained, a poultice of cotton wool strips soaked in de-ionised water was applied over the cracks and left to dry. This was repeated three times. Where required the cracks were consolidated with 5% Paraloid B72 (ethyl methacrylate copolymer) in acetone applied with a micropipette.
