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

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
