JSPAqua regia Gold Refining Supply kit, 3X 1/2lb Bags +Stannous Chloride with Instructions.

This kit is all in one and contains good directions for safe use. I would reccomend that a user of the product have a small collection of laboratory glass, safety goggles, rubber apron, gloves, boots, baking soda, a fume hood or well ventilated clean workspace, and basic experience in a college laboratory.

I was rather isappointed with this purchase because I bought it to collect precious metals from e waste, that's not what it's for,and it doesn't really tall you that. Also the directions for use are confusing, I ended up with a 300 dollar pile of green foamy gunk, the directions could be so much easier to understand its use if they didn't jump all over the place and repeat themself, also a precise amount of ingredients that you will need for each ounce of gold not a range of possible amounts.Clear concise directions would be the most helpful

You're better off getting your info on how and what to do from youtube. If you think this is going to make the process simpler,You're just going to get more confused. You can get more chemicals for less money from your local hardware store. UPDATE REQUIRES THE ENTIRE CONTENTS TO PRECIPITATE 10 OUNCES OF GOLD SCRAP....NOT WORTH IT!FOLLOWED THE ANIMATED INSTRUCTIONS ON YOUTUBE.IT'S ANIMATED BECAUSE IT DOESN'T WORK IN REAL LIFE.A WASTE OF SCRAP GOLD AND MONEY ON THIS KIT.I ONLY WISH I HAD TAKEN PHOTOS OF THIS FIASCO!I MIGHT STILL OF THE MUCK IT CREATED.WISH I HAD OF THE BOIL OVERS. WASTE OF MONEY!!!!!

The product would not get the gold into solution. Wasted countless hours of my time and money to come up empty handed.

Bad test solution, package arrived leaking acid

Chemical labels were switched resulting in one hell of a mess and the loss of 3 ozt of 18k scrap jewelry. Thanks guys you really cost me today
