Hi.
I'm not experienced Marquis tester and feeling somewhat insecure with the process.
I have something that was sold as MDMA crystal to me. I took a sample powder from the bottom of the bag and put it in to the test tube. I got insecure on the grey reaction (DXM?) though there is certainly purple too. So I went with another test tube. I've heard that it's better to use too little of the substance than to put too much. If one puts too much, it will just instantly go black and one can't judge anything on it.
Here are some images
There is some purple, but also brown/greyish
Another test
Notice the grey and the purple.
1st test tube where I put quite much of the stuff ended up purple though it had some grey to it inbetween.
What is your judgement on these pictures? Is this normal and acceptable behaviour? Ie. some adulterants but still one could call this as MDA/MDMA/MDx..
(I have more images if you are interested in seeing how the color changes in 5-10 sec delay)
