What just happened?

To celebrate Vikings Live, we have replaced our Roman alphabet with the runic alphabet used by the Vikings, the Scandinavian ‘Younger Futhark’. The ‘Younger Futhark’ has only 16 letters, so we have used some of the runic letters more than once or combined two runes for one Roman letter.

For an excellent introduction to runes, we recommend Martin Findell’s book published by British Museum Press.

    Bowl with celadon glaze

    This celadon bowl is rather damaged and in the past was restored with materials which over time have discoloured. It is a form made at several other kilns within China in the Southern Song Dynasty. The indented rim refers to silverware.

    Treatment proposal

    remove discoloured overpaint, reassess, clean and gap fill


    Old discoloured restoration along rim, this has yellowed. Surface inclusions inside the bowl on the glaze, possibly from manufacture. Light surface dirt.

    Treatment details

    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. Removed old overpaint with Acetone (propan-1-one/dimethyl ketone) on cotton wool swabs and mechanically with a scalpel. Old white plaster restoration and an old shellac fill underneath the plaster fill, these were removed mechanically with a scalpel revealing a large missing chip to the rim. The outside edges around the chip had been filed down mecanically and had removed the original celadon glaze. Running crack stained slightly yellow visible just below the missing area on the inside and outside of the bowl. Steam cleaned running crack and chip with de-ionised water. On running crack applied Ariel automatic (anionic and non ionic synthetic surfactants, sodium tripolyphosphate) dissolved in warm water and applied onto cotton wool swabs on the break edges. Covered with cling film, removed after a day and steam cleaned the break edges. Reapplied application twice. Allowed to dry fully for two weeks under a cover to prevent dirt and dust contaminating the clean break edges. Poulticed the running crack after with clean cotton wool and deionised water to draw out any remaining Ariel. Gap filled with Fynebond which was bulked heavily with Aerosil 805 fumed silica and coloured with artists' dry ground pigments. Gap fill was cut back with a scalpel and polished with Micromesh fine abrasive cloth (silicon carbide/aluminium oxide) grades 1500, 1800, 2400, 3200, 3600, 4000, 6000, 8000 and 12000. The gap fills were retouched with acrylic paints. 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.
