When I came back from the BGS with my last batch of slab samples I did not have a lot of time left. I started to sieve! I sieved relentlessly the rest of the week. All but two of the samples (I had brought 38) were done. It wasn't necessarily very pleasant; the wet lab is cold and splashing around with water doesn't improve things like that. But it was satisfying to see the pile of samples to sieve shrink rapidly!
