Barium Peroxide -> Hydrogen Peroxide
Decided to make Barium Peroxide. First I'll just make the oxide, and heat to 550 degrees, to create the peroxide.
Its about this step I want to hear from people who've done this before?
( Do I need to worry about oxidizing a crucible if metal? / Anything else.)
After that it all seems chill enough, add 30ml 50% Sulphuric Acid to 40g of the Barium Peroxide, get Hydrogen Peroxide by filtering out Barium
Sulphate. But yeah, feedback would be kinda great (please).

How do you plan on making barium oxide?

Heat barium carbonate or barium sulfate.
If you do sulfate then you capture the sulfur dioxide
And make sulfuric acid.

Which begs the question, what is your purpose for that chemical?
If you want to make green tracer composition or fireworks stars, more power to you. Where will you source your Magnesium or magnallium powder?
If you want to make -OTHER- things that require strong peroxides, have you heard of carbamide peroxide and sodium peroxide... Or of the various
concentration methods that require some time be spent with freezer or microwave oven and common over-the-counter Hydrogen peroxide solutions.
Just asking. You would learn valuable skills in manipulating equipment/conducting reactions and processes either way. And the concept that you live in
a glass house by asking any such questions on line by reading this reply.

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).

Note on recycling barium sulfate, an easier method is to convert barium sulfate to carbonate with sodium carbonate. You don't get sulfur dioxide out,
but you don't have to heat to extreme temps. Decomposition of barium carbonate still takes very high temps.

How do you go from sulfate to carbonate? The sulfate is also insoluble.

Boiling with a bunch of carbonate for an hour or two. Baking soda would be fine with slightly longer time.
I've done the whole thing, learning that hot and heavy Ba dusts are easily inhaled when stirring, and cheap BaCO3 of commerce is sometimes
considerably BaS, easily detected by adding acid and dying. And it's the worst way possible to obtain H2O2.
