Used in the process of refining gold. When refining gold to very high purity (99.95%+ pure), it is essential to use Reagent Grade (chemically pure) chemicals. Reagent grade is the highest purity available. This product comes with a link to comprehensive video instructions.

Quality is accurate to reagent/lab work
Good company. Had shipping issues with poat office and they bore with me to get it resolved. Purity on this is very good. Haven't had issues so far with reactions I've performed. I suspect this is pure enough you could use it for food preserving but I won't assume that.

It seems fine
I'm making a solution from this chemical to add nitrates to a saltwater aquarium and it is working well.

worked out well for my purpose.
I melted it in a lead pot and used it for tempering small leaf springs, worked perfectly. Will also work great for bluing small parts.

Fast Delivery but needs work on packaging
Decent amount, looks just like the image. Haven’t used the product yet but it delivered fast! Looks good but the package bag had a tiny little opening in the bottom corner when I open the delivery box some of it spilled on my floor.
