I want to do this calculation but assuming that the earth's crust melts, what values do I have to use for materials that are not solid?

Calculation of the melting of the earth's crust

For water you'd just assume vaporization, since if you're literally shaving away the crust you'll automatically vaporize all water bodies as well. Anything solid (Land-masses, tectonic plates, the oceanic crust and the continental crust and whatnot) would be melting, but I've had shit luck finding anyone willing to calculate the melting of the solid part.

What about Oxygen and Hydrogen?

Earth's atmosphere? Not sure if you could really do much other than just kinetically blow that away, but that'd require a timeframe.

I don't know, the original calculation mentions that the earth's crust is composed of 49.13% Oxygen and 0.15% Hydrogen.
I think the other calculation assumes that these elements are vaporized, which seems a bit strange to me.
I would like to know what I have to do with these elements for the fusion calculation.

Weird. Naturally I'd just go with rock as a low-ball for a crust and call it a day but uh... Latent heat of fusion is where I crap out hard.

Thought as much.

Yeah I was having similar thoughts. I originally wanted to just use granite for the crust as a low-ball but uh, 1. I suck at melting calcs and 2. Couldn't exactly find the average values for this feat.
In fact, most of it is silicates.
Using individual elements is not always helpful since they don't always exist isolated.

Most of the oceanic crust is basalt, and most of the continental crust is granite.
Most of the iron is hematite.
These are the sort of values you'd want to use instead of individual elements once you've divided up the Earth's crust.
So you can reasonably use basalt as the filler material for oceanic crust, and granite as the filler material for continental crust.
