Maria contiued to work at Perie's apparatus until one day whilst testing a substance calledpitchblende(沥青铀矿), she got a result that sent the electrometer off the scale, this was the highest reading anyone had seen, and since it was so much stronger than uranium, it must be coming from an entirely new element, the question was what was it. Since pitchblende was a mixture of different elements jumbled together, somehow she had to free her new element from the compound material.
In Marie Curie's notebooks, I mean she talks about starting with 100 grams of material, we're losing bits all over the place, you know it's really a substantial amount of rock, and this is really hardcore physical labour, you just got to pound and grind until you got a nice fine free flying material, and at that point, you can move really from the engineering into the chemistry, the next step is going to be actually trying to dissolve it up, and she'd have chosen nitrous acid because what you'd have known was this could dissolve...
