mixed with the small undiagnostic slag fragments. One piece of tap slag was recovered. This<br />
slag fragment had a funnel-like shape providing some impression of the space the tap slag<br />
filled/accumulated. The slag recovered from this context corresponds to finds 53 and 105.<br />

Context [6073]<br />
In the northeast corner of Structure 3, a deposit of burnt turf and slag was recovered from the<br />
bottom of the slag pit, context [6073]. Within this deposit, a concave ceramic fragment was<br />
recovered (Find 61), which has tentatively been identified as a possible mould fragment<br />
(Guðrún Alda Gísladóttir 2007: 69). This technical ceramic fragment was not examined<br />
during this assessment.<br />
Some smithing residues were recovered from this context, in the form of one fragment<br />
of a smithing hearth and a few examples of spheroidal hammerscale. Most of the slag<br />
identified is undiagnostic, however several pieces were attributed to smelting. The interesting<br />
aspect of this context is the three fragments of burnt bone that were identified. It is difficult to<br />
assess whether this material was related at all to the activities taking place, however, there<br />
have been references to the use of bone in smithing at other Scandinavian sites (Gansum<br />
2004). The slag recovered from this context corresponds to find 55.<br />

Context [6074]<br />
East of Structure 4, a deposit of turf and gravel was excavated, context [6074], which has<br />
been interpreted as collapse. One fragment of smelting slag was recovered from this context.<br />
This slag might be a furnace bottom, as indicated by the dense nature of the slag as well as<br />
the shape. However, furnace bottoms and smithing hearth bottoms are difficult to distinguish<br />
easily. The large charcoal impressions point towards iron production as opposed to smithing.<br />
The slag recovered from this context corresponds to find 55.<br />
