2 30: 0030 Rec. "br Fröet 4 $e F. 20, go2, CHINESE BRONZE TSUN Height. 33 cms. Diam. (top) 25 cms. Diam, (bottom) 16.3 " Weight. 5051 grams. Condition of metal: A massive object in bronze of high tin-content, showing occasionally (notably inside) the tin-like surface of they-eutectoid constituent and this is a natural phenomenon; the bronze has not been tinned. A crack beneath, which runs up towards the inscription, was formed during the casting but the metal is so solid that its strength is apparently unimpaired. Patina: localized, in parts well mineralised and can only be the result of long corrosion in the ground. Å Denåritic structure well developed in the cuprous oxide layer. Inerustation: occasional spots of incrustation appear where corrosion has penetrated beneath the surface skin. General Observation: The irregularities in the construction are of unusual interest because they provide evidence of bronze-casting from a piece-mould (14 pieces). It is only within the past year that fragments of actual siliceous piece-moulds have been discovered in China and made avail- able for examination, In this large bronze we have an excellent and undoubted example of an object made by this technique.
