Reason for treatment
Clean, dismantle, restick, fill chip
Old restorations with chips around the break edges, inside and outside. Old adhesive has stained yellow with age, and excess adhesive on original surface. Running crack stained yellow/borwn. Running crack from bonded sherds. Light surface dirt.
Glazed surface cleaned with a 50:50 solution of de-ionised water and Industrial methylated spirits (ethanol, methanol) applied on cotton wool swabs and dried with a paper towel. Dismantled sherds using Acetone (propan-1-one/dimethyl ketone) on cotton wool and covered with cling film. Removed cotton wool and picked excess adhesive out with a scalpel. Steam cleaned break edges and running crack a number of times with de-ionised water to remove ingrained dirt, dried with paper towels. Allowed to dry fully for one week under a cover to prevent dirt and dust contaminating the clean chips. Gap filled with Fynebond epoxy resin 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 (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 1500, 1800, 2400, 3200, 3600, 4000, 6000, 8000 and 12000. One area did not steam clean well, and still showed through after gap filling this area was retouched using Golden porcelain restoration glaze and Golden airbrush liquid colours. Object was further cleaned with a 50:50 solution of de-ionised water and Industrial methylated spirits (ethanol, methanol) applied on a cotton wool swab and dried with a paper towel.
