Very good teacher 👏

Thank you for this!❤ love your bracelet - do you have a video on making that?

Lit

I’m smelly

Thank you! This is the best demonstrational video of the technique I've found.

This looks great! Can’t wait to try it. How do you dispose of the solution when it’s been spent?

Thank you for this upload. I have used your tutorial a few times to remember as I always forget which is the annode and catode. Thanks :)

Cut the music. It is just distracting and unneeded.

5:34 what was that?

Never mind the liver of sulphur, you need to emphasise the importance of doing the electrolysis in a well-ventilated room. Electrolysis of salt water produces chlorine gas and hydrogen. The first will poison you and the second will blow you to bits.

I watched the video awesome,I am impressed this technique is so easily done,Thank you for the great videos!

Thank you for the tutorial awesome information, And I love that it's safe and there are no dangerous chemicals.

Can you etch aluminum this way?

I have some concerns about this process and I'd appreciate your thoughts on this... According to the metallurgist Midnight_cheeseater, on Reddit "Using saltwater as your etching electrolyte can be rather problematic due to competing side reactions. The main one, of course, being electrolysis of salt, which produces chlorine at the anode and hydrogen at the cathode. So you would have a toxic gas and a highly flammable gas to deal with."

Does it matter what size wire caps you use?

How do you attach the wire to the battery/battery holder?

Hi, I was wondering if any of the etched material that is left in the water requires special disposal? Is it just fine particulate of the metal or does the process make other compounds?

What do you use to pickle.?? ...Thanks for sharing.!!

Thank you very much! Please tell me where that I can purchase a dragon fly paper punch?

Oh Danielle. Boy do I wish that I knew this technic 55 years ago. Thank you for the information and the wonderful presentation. I had a little trouble with the audio. I will do my best to pass this along.

Thanks for this! Very easy to understand, and you cover all the bases. Great reference.

Thanks so much for this detailed demo! I'd never heard of this technique. I like that the solution uses no acid and it can be used "over and over again". Easier to dispose of too I suppose! I think I like the alligator clip method. Seems quicker, once soldered, than twisting the caps on and off for each project and probably easier for my arthritic hands. Would heavy duty clear packing tape, well burnished, work as well as clear contact "paper" for covering/resisting the back of the project? Thanks again!

bravo fah .

Please, could you tell me the reason to use distilled water? If I recon the water is saturated with table salt anyway.

Can I use house electricity??

What size of battery I need if I want to etch piece of copper 10 by 10 inch???

Nice work,simply explained,totally clear.Well done and thanks for sharing.May the road rise to meet you and the wind be always at your back.!

Nice! Thank you!

Hello, the silk screen also works very well and creates the possibility to do the drawing you want.

can the leftover water be used to electroplate copper onto something?

Can this be done on silver & bronze metal clay

Brilliant instructional video.Delivered in a calm unhurried and professional manner.A pleasure to watch.Moreover this video attracted many respectful comments which contained very interesting additional information.I have watched it often enough to have it etched into my memory.[Sorry,could'nt resist the pun].Seriously though,well done and thanks for posting.

will this work with brass? thanx

Thank you everyone for the kind and encouraging comments. We are all learning from each other, which is awesome! I will be teaching this to my high school students starting in March. Very excited to implement new and exciting techniques that can be paired with this method.

WHY couldn't YOU be teaching MY science classes when I WAS IN SCHOOL?? Terrific. Thank You! There IS HOPE for the U.S. educational system.

This is such a great video! Thank you for making it. I have saltwater etched before with several problems and it did not work ... your video is so clear and concise that I feel confident to try it again!

very clever and fine woman.

This was great!!! Thank you!!!

How are the wires attached to the battery?

What is the battery holder thing you buy from radio shack, I am in the UK and sadly we don't have a RShack, loved the store when I lived in Canada :) Jackie

I think, using acetone to clean off the sharpie after etching would be better than sanding it off.

Do you use scrape copper to etch brass or do you ne a scrape brass piece?

Will copper stain skin?

I can't wait to try this!!! I use lemon juice and salt for s pickle and this is also a safe & natural way to etch........thank you!!!!! It's like a science project!!!

do you have printed out version of this? thanks

How long will this solution last for, to be reused before it's not very effective? Can you put a lid on it and use it the next day?

can you use rechargeable batteries?

Is the 18 gauge wire that you wrap around the copper also made of copper?

Thanks for the video, Danielle. Definitely going to try this. Can you do more than one piece at a time?

Great video, I didn't know that we can etch with salt water. It willhelp for my future etched stuff.
