Graphene seems to be able to operate as a superconductor even when it is clumped and layers overlap. Seemingly it doesn’t have to be one molecule thick to have the desired effect. I have 3 types of graphene on hand for my experiments. The very expensive 1 molecule "single layer" graphene works only slightly better than the other 2. The other two are Arc Discharge versions, and nanoplatelets, and they are very cheap by comparison. I can hardly tell the difference in the strength of the effects between the 3 varieties. If anything, the nanoplatelets are the best overall, because they are much easier to handle. The single layer graphene is so light, it practically floats out of the bottle when you take the lid off. Way too hard to deal with!
You can definitely see it and weigh it. I do not recommend trying to smell it.
