you cant anodize copper can you?
Sorry, but nope. Copper doesn't form insoluble oxides, all you get is green corosion (which is slightly soluble).

if it is neutral, the concentration of OH- and H3O+ is 1x10-7 each. When it is acidic there is a higher concentration of H3O+ ions. and vice versa.

As far as I can remember there is no such thing as H+ ions by themselves

are there any aluminum anodizing kits out there??? how would i do that? sounds fun.. plus i wonder how they get all the cool colors on it...

That's all correct, I was using H+ for simplification.

There are kits out there for it. It's simply electrolisys to make the layer thick. To color the coating the kits just add a dye to the solution which gets trapped in the coating.

same thing as metal plating then right?

Not exactly. Almost the reverse, instead of depositing metal the voltage is reversed so that it tries to react with and disolve the surface, but since the compound is insoluble it just builds up.

It's such a pity that Al is so reactive, then you could plate the Copper with it and then anodize that. ;']

Still no sign of tarnishing on either metal, and the bubbles on the aluminium are gone now (I shook the jar and they didn't come back overnight)

DigitalChaos,

Maybe one thing to also try would be pulling out the metal once it has the black coating and seeing how easy it is to wipe off the metal.

If it comes off easily it could pose a problem in that if it keeps creating this black gunk, it could start to stick to other parts, or clog up somewhere else, like inside the radiator.

This would be one big worry as well

Cu setups are unlikely to poison you per se... most household water systems use copper piping. On the other hand it wouldn't surprise me if most waterblocks use lead solder which will poison you quite effectively

Still nothing, I should mention that I use normal tap water.

Edit : AFAIK virtually all water piping in houses are copper pipes... So it can't be that dangerous .

VERY interesting.... now im gonna have to try it with a heatsink like you..... just for fun drop in some aluminum foil, if you still dont get anything.... maybe my distilled water is acid or something

Nothing has happened to the foil yet.

the foil took a bit long... id say 12+ hours should start to show something but that was with the purple ice... with water wetter give it 24 hours


what brand was it? did it say aluminum on the box? (doubt it was anything but aluminum... but just to be save)


that is just crazy that you have not seen any black stuff

Actually the packaging stated that it was specifically developed to preserve the taste of the food or something like that

the mentioning of house pipes using all copper is interesting, how come in houses we have normal water flowing through copper pipes every day, and never a problem with any solids forming in the pipes?

It does form, in particular in hot water systems, just the pressure is sufficient to keep it clear.

maybe there is ... but being that copper is less reactive than aluminum, maybe its not a problem, plus its JUST copper piping... not much to react with except the minerals in the water.

good point though

ok, so it is the pressure that keeps it moving instead of settling down.

Is there any info about say a 100gph pump vs a 600gph pump and varying amounts of crud buildup? With the 600gph, wouldn't it just build up somewhere where there is no flow, like in the corner of a res or something?

In hot water circuits, naturally the build up would be more, so having a huge radiator, or just keeping the water temps as cold as possible would slow it quite a bit.

what about boiling normal tap water, and collecting the steam? this would ensure no impurities were carried over into the water

That's what you do when you distill water, so might just as well buy some.

i think he means pressure as in PSI not flow rate... because if you think about.. the only time there is flow in your copper pipe in a house.. is when you are running some water... which isnt very often compared to the non use time =)... a computer loop is on MUCH more....

also about the crud buildup... the pump flow wouldnt matter because of what i stated above... but the whole thing would be that there would be much less corrosion to build up... and therefore less of it to settle anywhere
