I have made one about 6 months ago (last i played) and now i need another one… However i can’t get it to work.
I toss a freshly made steel wrench in the bathing pot table and pour molten zinc (576 L, should be enough right?) using a ceramic jug in there.
I right click (use) the top of the table and it gets me the steel wrench back?
How did i manage to galvanize a wrench in the past?
Did you use Galvanized Plates to make the Wrench? You cant just throw the entire Tool into the Pot and expect it to work. 
There’s no recipe for the galvanized wrench using plates. That was the first thing i tried to do, then i remembered that galvanized tools are different.
I dont think that Recipe exists anymore now that I look at it.
Edit: I am gonna add it back though, because this was just some unintended error.
Alright, undocumented then i presume? i looked in the changelog for anything related to galvanized.
Oh well, i really liked the idea of having a set of galvanized steel tools for the durability. guess the wrench will have to be made using something else.
