It might help to have more oxygen in the mix. When the metal is fully submerged, it acts as somewhat of an insulator, and prevents oxidation. Maybe soak a paper towel, sprinkle some salt on top, and seal the container. Maybe open it occasionally to allow more oxygen in there. That's how I give copper a shipwreck patina, but I use ammonia instead of water/vinegar. Honestly, I am not sure that would help anything. Also, make sure your penny is pre-1982. Pennies after 1982 are mostly zinc. 🤷♂️
I thought this was a great experiment! I'm wondering if any other metals might work differently or if different dyes could be used? Very interesting, regardless.
Pretty cool experiment! I would recommend adding heat. I think thats what they typically do to agate slabs in south America with fabric dye.
Well at least now we know, thanks for doing this experiment.

Do you have a chronological list of your videos? I need to learn some terms. Thank you!
