One pinch of ash reacts with one drop of water to form "incredibly diluted lye".
You put some fine white ash in the large brown bottle. The fine white ash dissolves in the water to form some incredibly diluted lye.
"Incredibly diluted lye" looks like this:
This is a highly caustic yellow liquid used for making soap, about two tablespoons. It's still incredibly diluted at the moment - perhaps letting it soak in more ash would make it stronger.
If you add more ash (or if you initially add enough ash to react more) and wait a while, then the ash will turn into "leached ash", apparently indicating that it will not react further, and the lye will turn into a more concentrated version. Just waiting isn't enough: finishing the secondary reaction seems to require logging off, or perhaps manipulating the ash inside the container .
"Leached ash" can still be used for TPA and looks like this:
This is a large pile of leached ash, about two handfuls. It looks like all the colour has been leached out of it.
The amount of leached ash is the same as the amount of ash that reacted during the second stage.
There are eight stages of concentration, depending on how much ash you add.
They seem to be as follows:
|Stage||total pinches ash per 1 drop water|
|incredibly diluted lye||1|
|very diluted lye||2|
|somewhat diluted lye||3|
|very weak lye||5|
|somewhat weak lye||6|
All of the lye in the container will advance to the same stage, with any excess ash left floating in it. So if you add, e.g., fifteen pinches ash to ten drops of water, you'll end up with ten drops of incredibly diluted lye and five pinches of unreacted ash--as opposed to five drops of incredibly diluted lye and five drops of very diluted lye, for example.
The first seven stages all look like this:
This is a highly caustic yellow liquid used for making soap, about two tablespoons. It's still [stage] at the moment - perhaps letting it soak in more ash would make it stronger.
The apparently final stage, "lye", looks like this:
This is a highly caustic yellow liquid used for making soap, about ten drops.
Adding more water to lye that is above the "incredibly diluted lye" will dilute some or all of it to a less concentrated stage. This can result in multiple stages of lye existing in the same container:
The clear shot glass of very diluted lye, diluted lye and lye is about three-quarters full with ten drops of very diluted lye, mixed with five drops of diluted lye and five drops of lye.
One drop of water will dilute one drop of "lye" into two drops of "diluted lye"; one drop of "diluted lye" into two drops of "very diluted lye", and one drop of "very diluted lye" into two drops of "incredibly diluted lye".
Water doesn't react with "incredibly diluted lye", remaining unmixed in the same container.
The water appears to react first with the least concentrated lye that it can react with at all. For example, if the container has "diluted lye" and "lye", the water will dilute the "diluted lye" before it will react with the "lye", if there isn't enough water to dilute both.
Unlike in real life, it does not appear to be poisonous, nor does it damage you or have any other effect upon drinking it.
