Condition:
Very fine archaeological condition. The structural integrity is preserved, with a slight natural stress fissure along the rim. The surface displays remarkable ancient mineralisation, combining dark cuprite patination, green copper carbonates (malachite) and localised deposits of vivid blue azurite within the vessel.
 
This deep hemispherical bronze bowl rests on a rounded, slightly flattened base. Its walls flare evenly and harmoniously towards a straight upper rim with a thin lip. The restrained silhouette, devoid of incised or relief decoration on the exterior, is representative of utilitarian and funerary bronze vessels produced during the period of Han rule in northern Vietnam, particularly in the Red River Delta region.
 
The principal interest of this piece lies in the quality and richness of its mineralisation. The exterior has developed an earthy greenish oxidation crust, with areas of encrusted malachite.
The interior offers a striking contrast, displaying extensive green malachite crystallisation alongside well-preserved pockets of cobalt-blue azurite. These mineral deposits reflect the copper-based composition of the alloy and the particular burial environment associated with the archaeological context of the Han-Viet period.
 
The so-called Han-Viet period corresponds to the early period of Chinese rule over northern Vietnam (Annam/Tonkin), following the conquest of the kingdom of Giao Chi (Jiaozhi) by the forces of Han Emperor Wu in 111 BC. The period was marked by a fascinating process of material and cultural synthesis.
 
The region already possessed an exceptionally sophisticated bronze-working tradition, exemplified by the celebrated Dông Son bronze drums and ritual objects. Chinese administrators, soldiers and settlers introduced administrative structures, funerary practices including vaulted brick tombs and bronze vessel forms characteristic of the Han cultural sphere, such as bowls, erbei ear cups, lian vessels, lamps and mirrors.
 
Bronze vessels such as this bowl could serve both in the daily life of Sinicised elites and as funerary goods intended to accompany the deceased into the afterlife.
