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.

    Zhadou with dragons


    Zhadou (jar with bulbous body and flared rim) were used as spittoons, or vessels for leys or slops. This zhadou is incised with five-clawed dragons, shown in profile with clenched jaws, chasing flaming pearls and each other amid auspicious ruyi clouds. Potters inscribed a four (as opposed to the usual six) character Zhengde reign mark in underglaze blue on the base and covered the inside and base with a transparent glaze, then, before a second lower temperature firing they picked out the dragon and cloud design in green glaze on a ground of yellow. Potters working at Jingdezhen a century earlier, in the Yongle (AD 1403–24) reign invented this green and yellow colour scheme and design.

    Reason for treatment

    Permanent Exhibition

    Treatment proposal

    Clean, remove overpaint, re-do fill or retouch old fill.

    Condition

    Old restorations to rim on pot. Excess overpaint has yellowed and cracked and been applied by an airbrush, and is covering original surface. It is difficult to see what area has been filled underneath the overpaint. Light surface dirt. Enamelled decoration is very slightly scratched. Some chipping to the enamelled decoration.

    Treatment details

    Removed all overpaint with Industrial methylated spirits (ethanol,methanol) on cotton wool swabs. Old plaster gap fill under old overpaint, removed with a scalpel after softening with de-ionised water. Steam cleaned the chip twice 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. 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.
