0.2sArchaeologists often learn as much from where broken pottery pieces are found as from the pottery itself.
6.8sOne useful technique is refitting: researchers try to join fragments, or sherds, that once belonged to the same vessel.
14.9sNow, if two matching sherds are found several meters apart, that does not automatically mean the pot was used in both places.
23.1sThe pieces may have been moved after the vessel broke.
25.9sImagine a house floor with a hearth near one wall and a refuse pit outside.
31.6sSuppose several sherds lie beside the hearth, but matching pieces from the same pot are found in the pit.
37.9sA reasonable possibility is that someone swept part of the broken vessel out of the house during cleaning.
44.2sIn that case, the pit contains what archaeologists call a secondary deposit: material that was discarded or deposited somewhere other than the place where it first entered the archaeological record.
55.8sRefitting can therefore reveal how a site changed after objects were broken—through cleaning, trampling, rebuilding, or dumping.
63.8sBut a successful fit does not tell researchers exactly when that movement happened.
69.0sThey still need evidence such as soil layers, building phases, and the position of nearby artifacts.
75.1sSo refitting is most powerful when it is combined with other evidence about the sequence of activity at a site.
