I saw two digs handle pottery shards very differently and the results were night and day

I was reading about two sites in Turkey from the same time period. One team washed all the shards right away with water and brushes, which blurred the residue samples. The other site, at Catalhoyuk, used dry brushing and micro-tools first for over a week before any cleaning. Their lab got clear data on ancient grain storage from the residue, while the first site got nothing useful. It seems rushing the cleaning process can destroy key evidence. Has anyone else seen a small method change make a huge difference in lab results?

Yeah, that dry brushing step is so key. I read about a dig that almost missed parasite eggs in a burial site soil sample because they sieved it with water first. The water method broke up the fragile egg casings, but switching to a dry sieve and gentle air separation let them ID the species. It's wild how the first step can wreck the whole chain of evidence.

But honestly, water sieving is still the go-to for a reason. It gets rid of all that fine dirt way faster, which is huge when you're processing tons of samples. A dry method can let tiny particles cloud everything and hide the good stuff. Sometimes wrecking a few fragile finds is just the cost of actually getting through the material.

Wait, they almost missed parasite eggs because of water sieving? That's crazy... you'd think something that small would just wash away, not break apart. Makes you wonder what else gets destroyed before anyone even knows it's there.
