    Thanks for sharing your setup. What ratio are you using for the sodium bisulfate per gallon of Di water? I have some battery acid here but I'd prefer to try the sodium bisulfate first. Also which heaters did you go with? Nice setup.

    Thanks for the video. You have the closest setup to what I am building. As far as the anodizing bath, do you remove the cathode and aquarium bubbles when you are done or do you leave them in the acid solution? No one seems to talk about that.

    I remove the lead cathode and spray it down with distilled water, let it hang to dry. Then I clean it before use again. I do not remove the bubbler, since it is plastic.

    Hi, i once had a anodized bar of aluminum which had a black color tint from factory, with a sodium hydroxide and water bath solution it took about 15 minutes to release the black color and leave the aluminum color. The more time i left it on the solution the aluminum started to turn more and more WHITE . After doing that i spent several minutes with a kitchen sponge and cream with micro particules (normally used to remove stains in the toilet) to rub the surface of the aluminum for about 20 minutes, which started to release a grey paste. As i rubbed more and more i was able to get a "kind of anodized" finish. and if i kept rubbing more and more i was able to reach the more shiny aluminum finish. As cosmetics go, i never understood why for cosmetic purposes, this process left the color of aluminum more like a anodized mate look. Maybe i managed to get a nice result without using acid and electricity? of course im talking about no color, just real aluminum color.

    Nice set up. However, you will have an incredibly dangerous situation if there is a spill. You never want basic, nor alkaline materials in close proximity to acids. (YIKES!)

    Not that I’m aware of. But I don’t know much. I did switch to sulfuric, but my results are about the same. This is type 2 anodizing, which can be just about any color. Type 3 is “hard” is a thicker coating and requires more equipment to do. I think it can only be black or clear. Type 2 is still durable, much more so than Ceracote etc..

    I tried this and it failed, I got corroding pits all over it and it turned dark grey and took no color at all. Any guess what's wrong? It was pure unalloyed aluminium sheet metal hanging from a AlMg5 welding rod, I didn't etch it before but sanded the surface and cleaned it.

    You need the electrical current to anodize. The part is the anode and the lead the cathode. It's how basically any aluminum product is given a tough surface. Think Macbooks and iphones. You can learn more here. caswellplating.com/

    @@jasko346 I’m going to do another video updating on what I’ve learned but I’ll summarize real quick. 1. Fume extractor taking the air outside. Hydrogen is a little explosive and the fumes from etching are no joke. Mine is a 4” hose and 195 CFM in line fan (make sure it’s got no brushes in the motor or it could ignite the hydrogen) 2. GET AN RO system with pressure tank and make a little sprayer. About $150. This has made the largest difference in the quality so far. It’s a constant spray of clean water. 3. Put bubblers in your dye tanks to agitate and even out the temperature. 4. Keep tight Ph control on your dye.
