Product Reviews

Great Product and Price!

Great product and price for etching copper and brass. Not nearly as toxic as the other chemicals I was using and does the job quickly.

Great for etching blade steel

Worked great for putting an acid etch on my benchmade.

Big bottle great price

Works great for etching copper. I use it mainly for jewelry making, and I use allot. I was buying smaller ones at radio shack and it was just getting annoying because I wold run out and have to go to the store and get more and one bottle would last a little longer then a week. This big bottle is so much cheaper Then what I was doing before.

Bad batch? Didn’t work well for me.

I didn’t have much luck etching PCB with this stuff. With all the positive reviews, I’m thinking that this was a bad batch or old bottle I received. I suppose it’s still possible I did something incorrectly which is why I still give it 3 stars and so many others have had success using it. I tried heating this up in a hot water bath while agitating often throughout the process. The results were that it kept eating through the resist while still leaving patches of copper on the board and took well over an hour. Went through half a bottle and three different attempts and decided to give up on it. I then used a muriatic acid from the home store (hydrochloric acid ) solution and hydrogen peroxide mix (acid to base always!) in a 2:1 mix(peroxide to HCl). It worked great and was very fast as well as much cleaner since it is clear (changes to clear emerald green after etching) as opposed to the nasty yellow staining of ferric chloride. This method is also renewable by adding a little more (cap full) of peroxide. Do yourself a favor and lookup the Instructable on this method if the ferric chloride doesn’t work for you. As always, wear gloves and goggles and dispose of properly!

Ferric Chloride for etching steels.

I give this product 5 stars. It was packaged very well. I use it to etch Damascus knife blades and it works as advertised. I will buy this product again.

Fast shippong works great for etching knives

More Ferric Chloride for your money

MG Chemicals 415 Ferric Chloride Liquid, 1 Quart Bottle, Dark BrownI make etched jewelry. I use the Ferric Chloride to process them to achieve the design that I want etched into the various metals. I always bought my Ferric Chloride at a local electronics shop until they went out of business unexpectedly and was left to find a new vendor. I was excited when I came across it through MG Chemicals. I purchased a larger bottle for a comparable price. I will definitely be ordering more soon. I gave my friend this bottle and I am almost out of my previous manufacturers bottle.I highly recommend purchasing the Ferric Chloride through MG Chemicals.

Learn to Acid Etch Steel

I don’t get into all that nerdy PCB stuff (just playing!), but I do use this to etch designs into knives with custom heat transfer decals (photo paper and laser printer). This stuff works great… I think I’ve done 10 deep etchings or so on knives with the same bottle. No apparent reduction in efficacy.Did my review help you or do you have any questions? Please let me know.

Great,

Worked as expected, fast acting.

Perfect! Shipped quick and just as described

PERFECT to etch copper from a PC Board.A++++++

I needed this to etch copper off a PC Board that I had put trace runs from a schematic. This almost instantly dissolved the unwanted copper from the board and left my trace runs…

Works great

Use it for etching copper jewelry. Works great.

Great product

Really does the job

Works great!

Used it to acid etch a steel sign and it turned out pretty good for my first attempt!

Unimpressed.

Afterward, his engine block was undamaged. Very disappointed.

Works great

Works great and easy. I put mine in a bowl and then sat that in a dish pan that I let sit against the motor of my tumbler. About two or three for the results I needed
