|Loose surface dirt was removed using a soft sable brush & a vacuum. Ingrained dirt to the glaze was further removed using a glass fibre brush and a vacuum The surface was then cleaned by swabbing with a weak solution of non-ionic detergent in deionised water, which was then removed with swabs of deionised water only. Stubborn dirt was removed by swabbing with acetone.
A 10% solution of an acrylic resin was used to consolidate running cracks, loose ‘sounding’ areas of glaze and exposed areas of clay body. This was applied by brush and also micropipette.
The missing areas of glaze and small chips were mimicked using a coloured epoxy paste; a mix of a conservation water white epoxy adhesive, fumed silica and dry artist’s pigments. A large missing areas to the wall/rim of the ewer and the foot were reconstructed with a core-fill of plaster of Paris. Then, a coloured epoxy paste (as above) was applied on top to mimic the glaze.
Once cured, after 48 hours, the epoxy colour fills were refined and polished with various grades of sanding fabric. Finally, these were further toned with a mixture of a clear acrylic glaze, acrylic paints and artists dry powder pigments. The final layer was polished with various grades of sanding fabric and then with a plastic polish. Acrylic paints were used on the reconstructed areas of the foot rim to mimic the unglazed clay body.
