415-1L Ferric Chloride, 1 Quart

Works like a charm, careful not to leave it too long, does seem to eat it pretty well

I mix this 160z FC solution to 36oz of distilled water for knife etching in a 1/2 gallon glass wide mouth mason jar with a plastic lid and it works good. To see the best results leave it in for about 10 minutes and then rinse and use a wet sponge to scrub the blade. This will reveal just how dark your blade is. If you want it darker put it back in and repeat. This process will dull your blade so be ready to sharping when done or coat that part with fingernail polish. The picture is of 2 knives, one etched and the other in original condition. The whole process took less than 30 minutes. I suggest you wear gloves and safety glasses just in case and store this stuff in a manner that will prevent the container from breaking and keep some baking soda on hand for any spills to neutralize the acid. Be very careful that your metal parts do not drop in the jar. This could shatter the jar and leave you with a serious mess to clean up. If you get it on your skin dont freak out, it will take it a few minutes to do anything and if you rinse your skin with water asap it will not burn you. Keep this stuff away from pets that might ingest it. If they get enough your pet will have to be put down because the acid will destroy their GI tract and it will be a very painful death otherwise. On that cheerful note good luck and happy etching. :)

I have no issue a shipping the product was packed extremely well I didn’t leak whatsoever. I use this for acid etching my pocket knife and clip. I cut it one part acid, one part water and had each part in the acid for about 13 minutes. I saw other side of this was a weak version of the acid I have no comparison this is my first time purchasing, sorry. I will say if you’re using it for acid etching it will work clearly you can see the photos. I would buy again but I don’t think this acid ever goes bad. I hopr this review and photo are helpful.

That title says it all. This is ferric chloride etchant for copper-clad printed circuit boards. I t works fine; exactly as expected. I always found stuff from MG to be reliable and wysiwyg, which is why I like their stuff. Thanks.

Excellent for etching knife blades. Mix about 50/50 with vinegar and itll etch your hardened knife blades to a deep dark color quickly.

Good

I like that it's a fast acting chemical for etching copper although it is a harsh and somewhat hazardous concoction. That's the trade off if you want something that works quickly though so I have no complaints.

Worked fantastic for etching brass, i would buy again. As other have said be careful this will stain, i was poring back into its bottle and spilled some on the driveway, left a rust like stain. Also as you use/re-use this product it will weaken over time just be aware. What may have take 30 minutes the first time may take longer the 4th/5th/6th. i used rubber gloves to handle it which made checking progress easy. A simple mix of water and baking soda neutralizes it (good to know if you spill too) This started darkening my brass with in 20 seconds. Bottle says you can do from 2 minutes to 10 minutes. Since i was new i went 10 to see just how much it would darken. After 8 minutes i thought it had ruined my project couldnt make out any details i had etched, that was just build up. When i took it out a lot washed right off leaving a very nice grey/black color. Using fine steel wool i was able to lighted it where ever i wanted to bring out highlights.

Bon produit, il faut être juste patient

Buon prodotto, un po' in ritardo ma per colpa del corriere.
