I believe Russia is part of Asia?
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.
Anatol Rapoport was a Russian-born American mathematical psychologist (1911-2007).

Russia proper is Eastern Europe. The Asian part is called Siberia, and it's... somewhat apart.

Russia is too big for Asia and Europe, making up most of both continents . . .

Today I've run a batparatus again, on a different heat source: a camping butane stove. Everything went well, except for the fact that gas ran out at
the exact moment I started to distill the acid itself. Once again a consolation prize: 98% acid from the pot, made even happier by the fact that it is
now clear as water and not murky at all.
Repeat: I now have 200 ml (that's slightly less than 400 g) of real concentrated sulfuric acid. Not the watery Glover stuff I've been messing around
before. Real sulfuric acid, same as described in reference books. And I've made it myself. It's the color of cooking oil (my current batch was clear
as water, but the previous one was like castor oil), it is oily, it is burny, it is sugar-snakey, it is manganeseheptoxidelicious, it is CONCENTRATED!
It is SULFURIC! And it is an OTC Preparation in a country where the stuff is a listed chemical!

Are you using battery acid, ave?

Of course! 38% fresh battery acid. That's why it is called "the Bat". This is in fact a clumsy English translation of the word "Elik" which we call
it, short for "Elektrolit".

In my part of the world Bat apparatus would be equipment used in the Batcave:
The single most important condition for a successful synthesis is good mixing - Nicodem

Congrats ave. Nice result.
I'm happy to leave mine at 70% at present. But nice to have a procedure posted should I ever need to go the whole way.
And, yeah. You deserve your own tag.

Who knows, Batman is smart enough to invent such an apparatus himself...

Also, soon my Schott funnel and a jar of potassium dichromate arrive, and I'll be able to do more experiments with sulfuric acid, such as
Zintl-Karyakin distillation and freezing out. The last one requires the Schott funnel, but allows one to get monohydrate (100% sulfuric acid).

I used it many years ago and found it to contain SiC which coloured the acid brown as it decomposed in the hot acid!
The colour vanished as the carbon oxidised when the acid reached 98% and SiO2 precipitated!
I didn't bother decanting and used it as it was.
The SiC additive supposedly prevented the formation of long lead crystals which might otherwise short-circuit the plates . . .

Some of my battery acid samples display this behaviour too. But some color I attribute to brick boiling chips which partially dissolve. When the acid
hits 98%, however, most of this gabbledegak precipitates and the acid is fine and clear. Also, I find H2O2 a fine acid bleacher. It works with nitric,
too, oxidizing NO2 to N2O5.

If you have just the SiC additive H2O2 is unnecessary as hot sulphuric is, itself, a potent oxidiser!
