The mantle is between 500-4500K, meaning most of it is hot enough to glow at least a dull red.
You don't say lava is black because once it cools down it turns black...

Maybe OP does
I often forget we're basically living on a spherical hot pocket fresh out of the microwave.
Crispy Crunchy Tender Flaky Crust, Earth pocket!
Early scientific estimates of the age of the earth are underestimated it because they assumed the hot potato model, but radioactive decay keeps the earth hot for longer.
Oh yeah, well, em... the ocean called and they are running out of you! No, wait... damn it!
Here I thought the joke was going to be "The Earth is actually a complete sphere without having any slices or cross-sections taken out of it like that."
Related fun fact: The Earth's crust is largely made of feldspars: https://en.wikipedia.org/wiki/Feldspar

Bastards! What am I doing licking things, then?

Kerbal space program was right!

looks like a delicious matcha scone!
