hello, in the acid I can keep them as long as we want it's not a problem, even a month.
Since salt is not stainless steel, I can't find any useful results on that table. I just have to add some salt to the jar with just the water.

the acid reacts with the zinc. let's see what happens in the long run.
How long do you plan on keeping washers in this acid liquid?One more idea is to do long term test with salt water, some stainless steel is affected by sea and salt water and corrosion can happen for cheaper stuff.
This could happen if there is no molybdenum in stainless steel mix, but we never know this until we test it
Here is one example of mostly used grades of stainless steel, so better check out what type is used in your washers:

You do not need to click to "see it". Thumbnails maybe are a little too small but it is disputable, at least it saves transfer. IMHO there is nothing wrong in click to see it in "normal" size. And now I wonder if you talk about that click (from thumbnail to middle size) or about the next one, from middle size to "original" size. I like that idea, because "normal" size is enough to understand what you see, while "original" size is far too big, I see only a part of the image on my screen and I must scroll. Unhandy.
the pictures are really bad and I can’t see anything.
Click them 
I prefer images that be seen without clicking too.
Who am I to disagree?

Well done.
I don’t know if it is the image hosting provider that is downsizing the pro tires or you took them with a device from the 90’s.. but the pictures are really bad and I can’t see anything.

I'm back, sorry for the wait.
meanwhile I put 1 washer in normal water and 1 in h2so4 at 38%
the acid reacts with the zinc. let's see what happens in the long run.
instead for the test of several attached washers exposed to the flame here are the results.
I wrenched the nuts as tight as I could.
was in direct exposure for more than 5 min.
after letting them cool I unscrewed the nuts and some washers were attached, probably the impurities melt and cause this but it was enough to slam them on the counter to make them split. The incisions would not have been damaged under any circumstances.

The best place to hide something is the most visible place. Turn on fantasy and store seed phrases in the place where they will least search. Like in that movie, when the diamonds lay at the bottom of the aquarium among the pebbles and the glass.
if you want to hide them in plain sight, why not paint your words on a big painting and hang them on the wall:
prompt:
Quote
a matisse painting with the words "base","deer", "image", "close","depart", "bargain", "invite" ,"celery","brick","gap","able","caught"
safe = attention getter
Here's another idea: let them waste time on your safe, and hide your seed words elsewhere The safe can be used as a distraction and for storing small change (seed phrases with access to the minimum amount).

I see no problems there: close the curtains, get the power tools. Give me 30 minutes, and another 30 minutes to securely verify the seed words before funding the wallet.
I do DIY all the time. All my neighbors would hear is a bit of banging and drilling (just like when I host a Foxpup party). I could easily just be putting up some shelves or building some new piece of furniture. No one is going to suspect someone is engraving a seed phrase every time they hear a bit of building working going on.I don't need seed words to be readily available.
I have some wallets which I haven't accessed a seed phrase back up once since I set them up many years ago, other than to check the integrity of my back ups. But if the words are engraved in a safe and bolted to my wall/floor, then I can be certain the integrity is just fine unless my home has been destroyed. Didn't you watch all the movies where thieves steal the safe deposit boxes because they can't open them quickly enough, than they could bring it home and examine it from all sides?
That's why I said "the key is there", so it's obvious there's no value in it.I think most homes have safes, right?
Not where I'm living.safe = attention getter
Here's another idea: let them waste time on your safe, and hide your seed words elsewhere Engraving a list of 12 words on the back of a safe without no one around, and mounting that 30Kg box without anyone noticing the word list on the back of the safe, could be a tricky task, to say the list.

Same thing for the recovery of the seed.
Like I said, that's intentional I don't need seed words to be readily available. A physical safe is generally a good idea, too, especially when not using passphrases.
Hammer the words into the back of the safe, then mount it to the wall. You don't need washers if you have a 30 kg steel box.Engraving a list of 12 words on the back of a safe without no one around, and mounting that 30Kg box without anyone noticing the word list on the back of the safe, could be a tricky task, to say the list.

I don't think that's the case anymore since most people are living in tall buildings and flats, and I doubt each apartment has a safe.
People are still hiding their valuable things but they are mostly using hidden compartments or in walls, and some of them still trust the banks
I honestly don't know many people who publicly say they own safe deposits in their homes and I never saw it myself, but nobody is going to brag in public about that obviously.
Getting back to steel washers, most people do own some basic home tools and steel washers, so nobody would be interested in them very much
Fair enough, maybe it's a cultural thing or location dependant or even a generational thing. I know quite a lot of older people who are totally against banks, and have cash stowed away. They were self custodial-ing before it was cool to do so.

A lot of the olders houses around the UK have built in safes, and they're big bastards. You aren't getting it out without a bit of a struggle, and a lot of noise. Times are changing those, we're moving to the digital money age, and therefore houses don't come with them any more. Honestly, I don't think these new timber framed houses could hold a safe of that weight up anyway.
Yeah, steel washers with your seed could potentially even be left out in a tool box (although probably shouldn't be stored with expensive tools). Since, not many people are going to think twice about that. Not my particular choice of method, but I could see the reasoning behind it. Basically, anyone breaking into your house is looking for electronics, jewellery, and likely a safe of some kind. Since people are creatures of habit, they tend to store these safes in the same places too.
I think most homes have safes, right? Some houses used to come built with them in, and they were massive ones. You probably aren't going to be hauling that around, not far anyway. Most people put the deeds on their houses, and various other stuff in it. Unfortunately, they usually keep the key in the house, which obviously presents its own problems.

Didn't you watch all the movies where thieves steal the safe deposit boxes because they can't open them quickly enough, than they could bring it home and examine it from all sides?
If you have safe deposit at home it's obvious that you have something valuable to hide.
They're usually dumped not far from where the crime was committed, so you could potentially retrieve it again. That's if they didn't see the seed that is. However, I'd agree smash, and grab is far more likely than them taking the time or tools to get into a safe on site. Since, it either takes too long or makes a lot of noise.

Than you don't need your laptop, you can use your National Supercomputer Snellius for managing Bitcoin and Electrum wallet, nobody is going to steal that It's a feature, not a bug. Who's going to steal a safe if the key is there and there's nothing of value in there?
Maybe not inside, but it's outside the box.Someone who knows what you did (last summer) hammering that seed words on that steal box, could leak the information and someone could actually steal what is valuable.
