It could be ammonia, bleach, slaked lime. All of these can raise alkalinity in a room, greatly inhibiting HCN absorption, staining. You assume none of these were used, the most common cleaning products in Germany at the time https://chatgpt.com/share/687cd1d3-4cbc ... 4befc5ae22

I'm not trying to say I know WHY there wasn't staining, I'm saying you are not accounting for many expected/possible variables.

In re-visiting the Green Rudolf debate for this thread (as i do every few months, and you lot should too), i have found this from Dr Green. He is discounting your proposed mechanism of pH interference due to Lime or Whitewashing.

We therefore discount without further ado the possibility that lime from plaster or whitewash is a reason for an alkaline pH.

Dr Green - Chemistry is Not The Science

https://phdn.org/archives/holocaust-his ... e-science/

He is however, unusually silent on bleach

The AI, without prompting by me said the high pH would inhibit. I'm not a chemist so I would probably defer to Green here. The lack of iron seems to me to be a core argument by Green, how much iron is in a coat of whitewash?

Not much of anything is in whitewash, you ever use any? Mostly water. Provides very thin uneven coats, coverage is sporadic.

The iron quantities are measured and presented as follows:

I asked about the amount of iron in whitewash, according to Claude:

Traditional lime wash (whitewash) typically contains no iron or only trace amounts.
Lime wash is made from:

Slaked lime (calcium hydroxide) - the primary ingredient
Water
Sometimes small amounts of salt (to improve adhesion)
Occasionally casein (milk protein) or other binders

///

So the iron percentage in traditional lime wash would be negligible - typically well under 0.1% and often much less than that.

Does Prussian Blue form over whitewash? Are we assuming that if applied the whitewash would be splotchy, not fully covering the walls and ceiling?

An example of what I think "fully covering" looks like is this

Deleted - Seems like I made a mistake here that is easier to just erase

Mr Hill- Shows chart with known values of iron in the building materials of the morgues and the delousing chambers reflecting greater ppm of iron in the morgues than the delousing chambers.

CJ- just as we would expect, the reactive iron is lower in the morgues.

Me- did he look at the chart? The values on at least 3 samples where iron blue formed are lower. Maybe he doesn't know how charts work.

...I'm not a chemist so I would probably defer to Green here...

Also Bombsaway- doesn't, and continues to quibble about whitewash.

I appreciate a pun as much as the next man, but, Bombsaway, you can't 'Whitewash' away the results of the chemical analysis. I mean, the chemists don't.

This is another argument Du Jour, cooked up in your kitchen and served cold Sir. Not only are you not supported by the professional consensus, you serve it up and use as your support a picture of painted bricks taken from what might as well be space.

I'm not sure there is anything else I can say.

So prussian blue can form over fully applied lime wash, you're saying

the picture just shows lime washed bricks (not "paint", here's the site https://lizpacini.com/2020/07/30/we-whi ... ick-house/ )

I beg your pardon?

I'm saying that the lack of iron blue is not explained by a coat of whitewash. This also isn't just my opinion, but, is the opinion of the leading chemists that have studied this 'conundrum'.

That your opinion differs is not surprising to me. You are digging hard to find some seed to plant and have grow in to a reasonable doubt.

You aren't arguing special materials were used, at least, but, you are arguing that a coat of whitewash or a bottle of bleach explains the absence of iron blue. While novel, these arguments are not compelling to me personally.

To be very, very clear.

Concerning coverage and pictures, zoom in here;

https://i0.wp.com/lizpacini.com/wp-cont ... C768&ssl=1

An extreme close up would show you much better how little actual coverage they got. Looks good from the space shuttle though.

I haven't seen any "opinions" by any chemist stating about whether prussian blue would form over or under a thorough application of whitewash

the evidence suggests the chambers were painted or whitewashed (whitewashing is not painting technically but could be conceived as such, you made this error just above)

To which you replied 'I would defer to Green' and promptly, didn't...

Also, to be very clear, I figured the original picture of the bricks you shared via link was paint, as that seems to be more common. I was surprised to find that the person who did that, actually did whitewash.

Call it a mistake if you like, but, the mistake was to assume it was paint, as that is more common.

I defer to Green about alkalinity. It doesn't seem like he or Rudolf considered whitewash/paint as an element that could obstruct/inhibit staining.

Correct, and neither does anyone else really.

Again, it is thin and provides sporadic uneven coats, it also allows the coated medium to 'breathe' which is useful, not as a force field to block gas mind you, but, as a consideration to allow moisture, gas, whatever, to pass through.

Is whitewash waterproof? if they were washing down the walls after gassings which the witnesses suggest it would make sense to use a sealant of some kind. All of these things should be taken into account if you are making an argument of impossibility.

The delousing chambers which show staining were unpainted, or show no evidence of white washing. The ones that do (in Dachau, have no prussian blue staining, which Rudolf attributes to protective paint). You have to account for these variables, and you don't.

When it is set? It's pretty tough.

Catch it before it gets set up and you can wash it off, with not much effort.

Now you propose a whitewash and have added a sealer? What was the sealer pray tell? Got an invoice for it? Maybe it was lucite, eh?

this is just what the AI says

Surface-level resistance: Once dry, whitewash can resist light moisture and occasional splashes, but it is not waterproof like modern paints or sealants.

Indoors: In dry environments, it can last for years, but it will be vulnerable to wiping, scrubbing, or high humidity.

Chalkiness: Whitewash remains slightly powdery to the touch and may come off when rubbed, especially if not fixed with an additive (like casein or glue).

Whitewash is mildly water-resistant but not waterproof. It is suitable for dry or mildly humid conditions but not ideal for areas exposed to heavy water or scrubbing unless modified.

So considering people are going to be rubbing against it, throwing up on it, and then the walls get scrubbed it seems like they would use something or have to reapply it constantly. I think these are all reasonable inferences.
