Great product
This acid sure does the job just right and doesn’t let me down!!! Recommend this seller for trustworthy service!!!!
Super high quality… but not to be played with! Especially if you want to make aqua regina — just do NOT do it.. unless you have proper POE and fine hood. It’s not your average “home chemist”’stuff.. it’s highlyneffrctive to gold detection— but you MUST respect it with proper PPE of you will severely get hurt.
Quality wise— this is absolutely on par… I somewhat wish they would ship very small vials instead for enhanced safety. Anyway.. workers advertised… don’t do anything stupid!
Pretty excited to use this stuff for my gold recovery im sure it will do the job better than the other stuff I’ve been using!!! Fast shipping customer service is very helpful good people to do business with!!! Thank You!!! Will order more!!!
