Update to my previously posted Mandelin results. I obtained a further purified version of sample 4. Was told that it had gone through an acetone wash and was recrystallized. So, theoretically, it should be the same product as sample 4, but just cleaner. Visually, this sample is quite gorgeous. It looks like table salt. Very small, shiny, reflective crystals. Not powder, but the crystals are light and almost fluffy. Never seen product like this. The original version (sample 4) is also quite fluffy, but a bit more yellow in color. This stuff is white/clear.
So, interestingly, the mandelin result was different.
No green on this one, and straight to black with no smoke and only minimal bubbling.
Assuming that the supplier is not lying, this leads me to think that the green/smoking has to be from something that was washed or cleaned through the acetone wash and recrystallization process.
So, this leaves me wondering which one I should take. Do I take the unwashed, less pure product that has the green/smoking mandlin result, or do I take the product that is ultra purified? Also, I only have the $ right now to send one off to international energy control. Which one?
On the marquis test, this purified sample turned very dark purple. The purple reaction was absolutely obvious. It did not go straight to black. Even after it sat for awhile, it was a deep, dark purple.
