When dipping items to get rid of pesky fire, you can use much less liquied if you first move it out of a bigger container in to a vial. So you can use a full bottle to extinguish 10 items instead of 2. So PLEASE make it so you don't need to use vials in order to more effectively fight fires, I am SO bored of dipping vials into containers then dipping items into vials and doing it again again again.
We could probably switch dipping to work with the same volume of liquid as tasting?
The problem is, as you currently use dipping both to coat items and to move liquids between containers, you would then also move only 100 ml rather than 1/2 l of liquid. The question then is, what would it break and is it actually a problem?
