MG Chemicals 415-1L Ferric Chloride, 945mL Liquid Bottle, Dark Brown

Does what it does. Used to etch some brass plate. Did a great job. 10/10

bought this to etch a blade which had been polished to a mirror finish. I diluted this solution 4 to 1 with distilled/deionised water. (dont use it undiluted - you will damage your metal as its pretty strong stuff)2 lots of 15 minute dips in the solution and a perfectly etched blade came out the other end!Arrived on time, packaged in a thick plastic bag to protect from any spillages. 5 stars - would recommend

Etching some brass, the chemical worked well, this was my first time.Although I have made inked plates before, a similar principle. That was in college 20 years ago.So this was the first solo flight in a related field.I used a laser print ironed onto some brass plates.I was happy with the results, lots of spare liquid, I did about 15 small name plates.

Works as intended

Well packaged and works very well for building printed circuit boards and very quick removing the copper surface.

This is seriously useful - and extremely nasty - stuff. In solution, this produces Hydrochloric Acid and will eat through most non-vitreous and non-ceramic materials. Typically used for PCB etching (Google it), this also has use in "ageing" metal hardware (e.g. for "relic-ing" guitar hardware), which is why I buy it (I've seen the Schecter Guitar techs using this exact same stuff).This provides more than you need for that purpose and is sent in a good strong bottle that is over-sealed in durable plastic.Just be careful with this stuff and do not use without strong chemical-rated rubber gloves and eye protection.

Worked perfectly for bringing out an etched pattern on an antique wootz (patterned crucible steel) knife I had.

Great for making circuit boards, but be careful the whole time. Don't stop being careful even for a second, maybe have a friend be careful too for added safety.
