Reason for treatment
Clean chipped area, check appearance. Fill if necessary.
The object is stable. The rim presents multiple chips, some of the rim is worn and the coulor has varied. The surface of the chipped area is dirty, some of the dirt has penetrated under the glaze.
Steam cleaned chipped areas twice with de-ionised water to remove ingrained dirt, dried with paper towels. Applied Laponite RD (sodium magnesium lithium silicate) onto wet Japanese tissue paper over the chipped areas in order to drag out the dirt inside the glaze, the Laponite was covered with cling film to slow down the evaporation rate. It was removed before fully drying and the rim was steam cleaned to remove the Laponite. The Laponite was applied more than twice, the object was steam cleaned in between each application. The Laponite removed some staining, but not all. Applied Ariel automatic (anionic and non ionic synthetic surfactants, sodium tripolyphosphate) dissolved in warm water and applied onto cotton wool swabs on the chipped areas. Covered with cling film, removed after a day and steam cleaned the rim.The object was allowed to fully dry for one week under a cover to prevent dirt and dust contaminating the cleaned rim. The rim was gap filled where necessary with Fynebond epoxy resin which was bulked heavily with Aerosil 805 fumed silica and coloured with artists' dry ground pigments. The resin was applied with a metal spatula, a core colour was applied before applying the surface colour. The resin was allowed to cure fully for 2 days, then softened with Acetone (propan-1-one/ dimethyl ketone) 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 further cleaned with distilled water and a few drops of Synperonic X, using cotton wool. After cleaning, the surface was rinsed with distilled water on cotton wool. The surface was wiped with a dry Kleenex tissue to remove any remaining distilled water.
