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

Works really quick on circuit boards the first one was less than 5 mins. For a 70mm X 50mm board.

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

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

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.

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

Works as intended

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.

Bought for etching Damascus knife steel and it does it perfectly. Diluted to your preferred strength this will be fit for multiple etches. Predictable and repeatable results with each bottle which is half of the battle.
