Metallographic Description

Dendritic, heavily corroded. There is not much structure visible in the dendrites, though at high magnification coring can be seen. What may be lead particles are numerous, although the elemental analysis shows only 0.8% lead. Notable are round areas filled with gray corrosion product that shows distinct grain boundaries inside them; they look like the remnants of corroded redeposited copper.
