The site's most intriguing feature is the presence of a substantial and very early iron smelting operation, as evidence by large quantities of slag, technical ceramics, furnace remnants etc.
At that point in time, domestic structures, at least in the excavated areas, cease to exist, and are covered, without a clear interruption, by a stratigraphically well defined phase of iron production.
This phase has a complex internal layering, likely reflecting seasonal activity over an extended period of time.
This phase consists of large quantities of various types of slag, most belonging to a bloomery iron smelting operation, and a fraction to primary smithing (i.e. bloom-smithing or bloom consolidation).
Based on examination of the extensive pottery finds from this post-smelting phase, it can be assumed that the iron production activities must have ended no later than 750 BC.
No settlement structures contemporary to the iron smelting phase are presently known from Tell Hammeh.
