Anyone have a source of Hydrogen Peroxide?

Need a litre or two of at least 60 Vol (18%) preferably much higher.

In case you are wondering, this is the second stage in stripping chrome from plastic, this time my fluorescent lights. Modified quote from Borough Plating, the company who stripped my portlights [with thanks to FullCircle who organised it for me]:

The chrome deposit is stripped first of all using a 50% solution of concentrated (36%) Hydrochloric Acid at room temperature.

Once the chrome is removed, the nickel and copper layers can be stripped using a 10% solution of concentrated Sulphuric Acid (96%) and Hydrogen Peroxide (100 Vol, 30%). To make up 1 litre you would need 100ml of Sulphuric Acid and 100ml Hydrogen Peroxide, decrease water and increase quantities if lower concentrations used.

This strips best at 40-45 degrees centigrade. Neither solutions require electrodes as they work chemically.

I also need a vessel to strip in, ideally 400mm tall x 60mm diameter; thinking rainwater pipe, if I can seal the bottom.

Why? Googling will show you that it is perfectly possible to buy some of the most hazardous chemicals, e.g. fuming nitric, concentrated sulphuric, apparently even benzene, a solvent that has been unobtainable in UK labs for years. Dichloromethane, a paint stripper that is banned for both amateur and professional use throughout EU and USA is available in UK by mail order. Compared with them Hydrogen Peroxide is pretty harmless stuff.

Can be used as one of the chemicals in a bomb. As a kid my father and I used to make explosives to power the rockets we made, it would probably be illegal now. It's amazing what you can use to make explosives which can be found in the house and shed. I'm not telling what for obvious reasons.

Some terrorists though have converted low concentrate HP to high test HTP, a very effective oxidiser for both rocket fuel and explosives. Strange what you can achieve with hairdressers supplies. Mind you knowing just how reactive HTP is I for one would be reluctant to have it in my kitchen never mind make it.

It's not such a bad material, I fact it's a wonderful solvent and blowing agent/ paint strripper. Early, flawed research on mice concluded it was a carcinogen to them. True. That was extrapolated to mean it was a carcinogen to all mammals . The EU took their usual approach and banned it. Subsequent research by ICI revealed the biological pathway affected in mice was not present in higher mammals; not even rats !

Also anaesthetised your odour sensors, so you could no longer smell it, so didn't know you were breathing it.
Any, even trace vapour drawn through a glowing cigarette end, can be converted to phosgene, which is toxic even at low concentrations.

When I was a lad I got hold of some 100 volume hydrogen peroxide (you could buy it in chemists' shops) and thought I would test its bleaching powers. What was the strongest colour I could lay my hands on? Why, that would be the jar of potassium permanganate I had lying around. So I stuck some peroxide in a flask and lobbed in a scoop of permanganate.

Forty years earlier and I could have sold my discovery to Wernher von Braun. The ceiling never really recovered.
 
Regarding Phosgene. As a child, my home chemistry book gave a method for making a fire extinguisher: break the tip of a light bulb under the surface of Carbon Tetrachloride; the bulb fills up making a Phosgene bomb when you drop it on the fire. https://en.m.wikipedia.org/wiki/Carbon_tetrachloride#Historical_uses

Tried it, I can still remember the smell. I think I need to check my Halon extinguisher ...

Brilliant!!!

Anyone with moderate chemical knowledge (probably not even to A-level standard) knows enough to make a bomb from readily available materials. You can, at a pinch, make one from flour and nothing else - it's probably how they did the stunt in "The Italian Job" that was followed by the immortal line "You're only supposed to blow the doors off!". Explosives are pretty easy to make. There's a line in "The Martian" - the book, not the film - where the chemistry expert on the space-craft says yes, he can make an explosive - his training is all about how NOT to make one accidentally!

Making SAFE explosives and useful detonators is another matter entirely. But the average terrorist isn't too worried about H&S!
 
We used to use sodium chlorate weedkiller and sugar. The IRA used to use sodium chlorate and diesel, apparently. Sodium chlorate has been fixed to nullify its explosive qualities but the other two are unlikely to be banned.
