Thanks Avra. Now all we need is someone to find a way to use pepper to tin the finished tracks. :lol:

Yes! I saw that. Interesting.

I have a bottle of Ferric Chloride, but I think I won't buy another and go with HCL and peroxide. With or without a pinch of salt.

As far as tinning the finished tracks, perhaps hot sauce?

In my humble opinion, I'm always right.

His method does not use HCL ... just vinegar, hydrogen peroxide and salt.

Um, yes! You're right. Better watch the video again and take notes before I try it

Um, the posting says:

Quote:

NEWSFLASH : Just when I thought this story was done with – I just tried adding a sprinkle of salt to the (already) potent mix of Hydrogen Peroxide and Muriatic Acid – Dang! It etched the whole board in under a minute… Wow! Definitely some kind of catalyst. Resulting solution is bright green (CuCl2?), not the usual blue.

Ignor, what's the interpretation?

I agree there is an inconsistency in his written and video versions. I am hoping the video is correct ... as in actions versus words.

Cheers,

Ross

Use pepper for sneezing, and see if that thins the tracks :lol:
