I have some work for you, if you’re interested.
The Clothier is nothing if not relentless with his requests for more flux. Flux is a general cleanser and is used for many things including the tanning of leather. It is a simple solution - simply mix a flask of water with crushed rock salt until the salt is thoroughly dissolved, then heat the mixture until it changes color.
Bring me 3 vials of flux, and I’ll pay you for your effort.
