Copper (II) Chloride dihydrate Reagent 99+% with cert. - 125gm

So, it was difficult to decide exactly how to rate this product because, it definitely did what it was supposed to do; turn the flame pink, but, it was incredibly brief and akin to a fail.There were nine people to reveal the gender to and two people actually saw the flame turn pink but that's Only because they were watching so intently. It was frustrating. However, there was a reason for the 'fail' and it's not due to the product failing. The problem was in the AMOUNT of powder that I used with the size of the fire.When I'd experimented with it prior to the gender reveal party I'd poured a heaping capful onto a very, very small fire...a small enough fire that I could just step on it a couple of times to put it out. I was quite happy with the results of that experiment; the amount of powder vs fire size resulted in a brief, but beautiful deep magenta-colored flame.At the actual event though, I'd split the remaining powder (which was essentially the entire bottle) into two paper bags in order to allow both parents to pour the powder over the flame simultaneously. I'd kept the lid on tightly from the time I'd received it up to the time I split in between the 2 paper bags, only opening the bottle 3 times: briefly upon receiving it in the mail to look at the contents, briefly for my aforementioned experiment, and the final time was splitting it up. And there was only about 10 days in between receiving the bottle and using it at the event so, unless it had been exposed to air prior to its arrival at my house, there was no way I did anything to lessen the potency by leaving it exposed to air.If I could do it all over again with this knowledge, I'd buy either a much larger container of powder or multiple containers. The timeframe of color change would still be brief but more powder would create that deep magenta-colored flame I'd experienced previously.So, if you're going to use this for a gender reveal and cannot find a larger amount then buy at least 4 of this size and as close as you can get to the timeframe of reveal go ahead and put all the containers of powder into one single container. (Like I mentioned, you want to do this as late as possible so there's as minimal time possible for the powder to be exposed to air which will lessen its potency)Lastly, be sure to pour all of the powder as quickly as possible.Good luck!Oh, the fire I was working with at my party was a typically sized campfire; ours was built in a firepit.

Used for a science project that eats away at aluminum. Did exactly what I needed and expected!
