Stannous Chloride To The Rescue!
It seems I already reviewed this product and so was surprised to see yet another email from eBay, on a $7.00 purchase no less, but being a good sport I'll go along with the request. Now, anyone who works in gold refining already knows that stannous chloride is one of the tools commonly used to identify whether or not a fluid has several different precious metals dissolved in it. So no use mentioning that. And they probably have already made their own stannous from time to time and know all about what it's made from (tin dissolved in acid) so about the only thing left to talk about is convenience and this product is very convenient. All you have to do is unscrew the lid and put a drop on a drop of the suspect liquid, in this case my gold standard solution, and see if it turns black or not. And my bottle did in fact work and I therefore am happy with the product.

Professional product ...
I gave up making my own after making one test :)

One of the classics that everyone should see ...
This was a gift for an expert on the movie (there must be five or six versions out there) and she says this is the Best Version :)
