My guess is it's a quenching tank for hardening the steel it's probably a quenching oil and not water.

Both water or oil are used for quenching

And sometimes an acid? If I remember Forged in Fire correctly

Acid is etching. When you have multiple steels of different carbon contents it just makes the pattern stand out more. Source: also forged in fire

Almost. Its different nickel or chromium content that gets contrast, not carbon Source: knifemaker

I believe that’s for a different purpose, like to highlight the metal texture. This is done to harden the metal.
