Reason for treatment
Light surface dirt. Old restoration to one running crack, which has been riveted on the outside of the dish. 5 stained running crakcs visible inside and outside of the dish. Minor manufacturing flaws on glaze. Surface is slightly scratched. Part of old paper label on base is slightly loose.
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. Steam cleaned running cracks with de-ionised water, avoiding the old riveted restoration. Applied Laponite RD (sodium magnesium lithium silicate) onto wet Japanese tissue paper over the stained running cracks and covered with cling film to slow down the evaporation rate. Removed before fully drying and steam cleaned all the cracks. Applied Laponite three times, steam cleaning 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 cracks. Covered with cling film, removed after a day and steam cleaned the crack, applied twice. Applied cotton wool dapmened with clean de-ionised wtaer onto each crack three times to remove any remaining Ariel. 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. Consolidated rivet holes with 5-20% Paraloid B72 (ethyl methacrylate copolymer) in 50:50 Acetone (propan-1-one/dimethyl ketone) : Industrial methylated spirits (ethanol, methanol) applied via a brush.
Porcelain dish with rounded sides. Pale liver coloured glaze derived from copper, mottled darker pink in some places, with a few dull greenish patches on the back. Mark in underglaze blue on base.
