Pyrogallol now cost £1 per gram in the UK ...
Eli, most of what you say is right, but things have been changing and continue to do so. You mention for instance borax and boric acid, and while with a little bit of effort and luck you can still get those, here in Europe it's getting more difficult for private individuals. Sodium hydroxide is a notable other example that has become more challenging to obtain (there are still ways though), copper sulfate is not as commonly used everywhere as it is in the US as e.g. root killer (I've never seen it sold for that purpose where I live), battery acid is not easily obtainable anymore either (it used to be, but no longer), hydrogen peroxide (for e.g. reversal bleaches) only in concentrations that aren't effective for photographic purposes, the same goes for other acids although those are generally still useful in lower concentrations, etc.
That's just not realistic. You don't go and suggest that people use aqua regia to make their own gold chloride etc. That's just silly - and highly irresponsible. Even making silver nitrate with nitric acid is risky business - and by far not all that easy to do if you need the purity that is required for photographic purposes.
I agree that with sufficient creativity, there's lots of stuff still to experiment with. But you can't (shouldn't) deny the reality that many things that you take for granted really are not as easy to get elsewhere than they are for you. Ask any darkroom worker in Australia or Brasil how they fare. You'll start to understand how spoilt rotten you really are.
Unrealistic given the diversity of sourcing situations and the every-changing rules & regulations. You could write a book and it'll be (1) incomplete and (2) outdated before you even get halfway.
suggesting a sticky thread would be outdated anytime soon is just not a defendable assumption, just serving in the role of a blocking censorship of photographers from even attempting.
It is more a comment on how the forum structure and its international nature isn't well suited to what you wish to achieve. Advice that works in the USA is often merely frustrating to those of us who aren't in the USA.

hydrochloric acid for B&W reversal processing
In your case, I'd guesstimate it's a mix of both valid concerns and perhaps some people (I'm not mentioning your wife of course...or perhaps I am! - don't tell her!) being overly cautious. Then again, if you have pets &or children running around, it's already a different matter than working in a place where you can be confident nobody is going to take a sip from the bottle of attractively orange juice (which then turns out to be 10% ammonium dichromate...) Risks and concerns should be taken seriously and sometimes, in the negotiation between members of a household, this means that some things may not be feasible. Being forced to choose between reversal processing and a happy marriage, I'd gladly shoot digital!Sometimes with decent reason, sometimes due to (IMO objectively) odd/irrational reasons.
The harsh reality is that many of them are absolutely unwilling and unable to do the things that you and I may consider all in a day's work.
In that vein, living in very close quarters with a dog and wife,
Phototrio.com is one piece in that base, so let's share and in doing so become more united in our aspirations of better tomorrow
I have one in particular, which has a number of pages dedicated to photography and darkroom chemistry, using some house hold items, etc, and it's an interesting read, if only for learning what was done in the past.
Censorship is often social, not governmental, but more like the prohibitions of the European Guilds, where if you were not in conversation with or teaching an apprentice, any 'how-to' knowledge was censored by the members.
Today, censorship is quite common, which is, IMO, is ironic, seeing how the Internet is suppose to be the portal to (near) unlimited knowledge.
I believe this is true, but since this must take into account different availabilities.I have zero concern about black and white chemistry. If people could figure out how to develop in 1880, we can surely figure it out today. Cost is another thing altogether.

Do you have a favorite alternative to photographer's chemistry store product that you're willing to share here?
Unless your dog reads your Photrio posts, it might be more politic to post instead "In that vein, living in very close quarters with my wife and a dog".

sulfuric acid
Oops yes, it was sulfuric acid I was thinking of. I remember looking into it briefly, and in the USA, you can buy it at Walmart.
I have no desire to work with strong acids and caustics. I worked as a chemist, analytical, old school. Kjeldahl nitrogen assays, boiling sulfuric, 50% NaOH. Nitric and hydrochloric digestion of mineral specimens. Never got hurt, freaking miracle, neither did any co-workers.
I will stick to buying the non-hazardous stuff.
I did make a batch of silver nitrate a couple years back. Beautiful crystals. Very toxic fumes.
if you have the space to put a prepared barrel with hardwood white ashes (no charcoals) and safely trickle water through them to a secured safe catch jar or bucket.
college printmaking studios, where the use of Acids is just part of the process in copper plate etchings, sugar etchings, etc.
