Everyone should understand this, but there's a Chicken Little in every crowd.
The most fundamental lessons regarding grinding vs heat materialize immediately. You have a chunk of steel, you put it against a belt, and you hold it there. Soon it becomes warm... then it becomes uncomfortably warm.
OMG. What now?!!
Many will spot the omnipresent bucket of water right beside the grinder, and toss the blade at it. Lesson 1... check.
You may think that heat generated by grinding would require a PhD in quantum thermodynamics to solve. Nope. Start grinding the bevels on one blade and you will automatically be dunking the knife before it gets too warm. It's either that or you let go of the blade and wait until it cools enough to pick it up off the floor.
All the cool kids will be dunking their blades and laughing at you.
It can't take long to fully appreciate that uncomfortable comes shortly after warm. Hot comes later. Seeing color is a different realm of hot, and falls under Grepper's applicable term- "grossly overheated by incredibly poor sharpening practices".
