Intersting Technique

[Minimalist]

Could just be an oversight but, as kb notes above, none of these procedures are fool proof.

I think the thing with a fire big enough to 'reset the clock' is that it will leave evidence of that fire. So, for example, if we have a pottery shard in the Megiddo Level II destruction layer and date it to 3,500 BC and a pottery shard in Level III which was also destroyed by fire and that shard also dates to 3,500 BC, we could assume that the fire in level III reset the clock for the pottery in Level II. At such point, there is nothing to stop archaeologists from using the pottery-type database to get a date for the Level II shard. In other words, this will be one more tool in a collection of tools but not THE tool.

What I suspect it will do is replace C14 dating of associated material which is not terribly accurate anyway unless you are lucky enough to find something that was being contained in the pot in question.
