Does multiple-layer graphene intercalate alkali metals as graphite does? If not then that might be a way to test it. Attempt to use the product to
synthesize something like potassium graphite before and after treatment.
Got some 500 micron-thick graphite foil on the way myself and fancy experimenting a bit in this direction.

Alkali metals generally intercalate graphite , from what I can remember sodium and magnesium are not good intercalanting agents. You can soak graphite
foil in anhydrous alcl3 dissolved in some ether, dry the graphite and heat it or throw water on it and the graphite foil will exfoliate to few layer
graphene like the viktor petrik trick.But its dangerous.

Presumably danger is of course dependent upon scale and how much H2O is used as well as the thickness of the foil. I shouldn't imagine use of a large
volume of ice cold H2O on an experimental scale poses a great deal of hazard. Cooling externally with an ice-salt-acetone bath or similar could be
helpful, to avoid a sudden severe exotherm.
Or does the process of exfoliation partially or wholly rely on the temperature change and expansion between the layers of graphite, forcing it apart
from within due to the pressure change when the AlCl3 hydrates and presumably, on the microscopic scale, starts steaming within the layers of
graphite.
The graphite foil arrived today, its funky looking stuff, flexible, as though like a soft metal like lead.

The hydration is exothermic.

Looks like I'm going to have to get a replacement. The seller I bought the graphite foil from didn't pack it too cleverly, and there are kinks in it
in various places, and additionally, there is a relatively deep impression of the address written on the envelope which has carried through to the
graphite. They obviously wrote the address on the package after enclosing the product and wrote with a hand heavy enough to indent the foil. Probably
not so great for electrical experiments involving materials like graphene

Just rub some acetone on the ink no need to get a replacement.

It isn't ink. The problem is that the sender pressed hard enough whilst writing to carve the address into the graphite itself, and its full of kinks
and surface cracks. Its quite literally gouged in, and no washing with solvent is going to remove that.
