Dish with celadon glaze
This celadon dish with flattened rim is one of the most common products of the Longquan kilns. These celadons were made in the south-western part of Zhejiang province in the area around Longquan in the Ou River basin. Longquan clay is light grey but re-oxidises during the cooling process in the kiln, so that it can appear orangey-red where it is unglazed. The Longquan kilns were non-official kilns.
Stoneware, porcelain-type, with celadon glaze

Reason for treatment
Dismantle, reconstruct, fill chips.
The object has been reconstructed in the past. It has three fragments, the joins have yellowed considerably. The adhesive of the joins seems to be failing, the joins are not aligned properly and some present small gaps. The object also presents a few chips on both sides.
The object was dismantled using Nitromors *NITW* acetone soluble (methylene chloride,sodium hydroxide) applied with a paint brush along the joins and covered with aluminium foil to decrease evaporation. Once the joins were dismantled the Nitromos was removed with cold water. The adhesive on the join interfaces was removed with a scalpel. Then the interfaces were steam cleaned to remove the staining and intricate dirt. Allowed to dry fully for two weeks under a cover to prevent dirt and dust contaminating the clean break edges.Fynebond resin was let to gel for a while and then applied on the break edges with a spatula. Then the object was reconstructed by securing with masking tape. The excess of epoxy was removed with acetone on a cotton wool swab on a satay stick and a scalpel blade. The chips were filled with Fynebond which was bulked heavily with Aerosil 805 fumed silica and coloured with artists' dry ground pigments. Resin was applied with a metal spatula, allowed to cure fully for 2 days, then softened with Acetone on a cotton wool swabs and shaved back to the correct size. Resin was allowed to cure for a further 2 days before being polished with Micromesh fine abrasive cloth (silicon carbide/aluminium oxide) grades 2400, 3200, 3600, 4000, 6000, 8000 and 12000. The object was cleaned with distilled water and a few drops of Synperonic X, using cotton wool swabs.The surface was then rinsed with distilled water on cotton wool and wiped with a dry Kleenex tissue to remove any remaining distilled water.
