Reason for treatment
Dismantle, clean, re-bond, fill as required
Object has been broken into many pieces and bonded. Adhesive from the restoration has yellowed as have the epoxy fills in areas of loss.
The object was cleaned with deionised water and a few drops of Synperonic N (non ionic detergent, nonylphenol ethylene oxide condensate), using cotton wool. After cleaning, surface rinsed with deionised water on cotton wool. Surface wiped with dry lab tissue to remove any remaining water. The adhesive was tested for solubility and results showed that dichloromethane (DCM) was the appropriate solvent. The bowl, supported with tissue, was placed in a desiccator with dichloromethane for approximately 3 days after which time the majority of bonds has failed. Smaller joins were dismantled with Nitromors water soluble (dichloromethane, sodium hydroxide,cellulose). It was necessary to apply Nitromors to some break edges to enable the removal of adhesive. Fragments were cleaned under cold water followed by steam cleaning to remove adhesive and dirt. Fragments were left to dry for one week. The fragments were reassembled using masking tape to secure. This was carried out under magnification to ensure exact alignment. Fynebond (epoxy resin) was applied to all breaks by capillary action. Excess adhesive was removed before fully cured with acetone on cotton wool swabs and a scalpel. This was repeated after curing to ensure no excess adhesive remained. Areas of loss were filled with Fynebond bulked with Aerosil 805 (fumed silica) and coloured with dry artist pigments.
