Havent seen this asked before. A quick search showed me nothing.

What chemicals other than MDMA could make a black Marquis reaction?

From my experience I have only ever seen it go instantly black twice from "MDMA" powder.

One of these times was today when I was offered "MDMA". It came wrapped in foil, was almost red in colour and looked very wet. Almost like red jelly crystals with a little bit of water mixed in.

Some friends tried it and they said that it was ok but not great. Not sure of all the details. Maybe they didn't have enough or maybe it was badly synthesized.

My question is how many other chemicals would make a Marquis reagent turn black (not purple, not dark blue but BLACK).

If Methylone (MDMC doesn't turn it black then surely there arent many chemicals that would.
 
You should test it with Mandelin as well. I've had completely dud pills go instant black on Marquis but then Red on Mandelin. Also I'm pretty sure MDA goes black.

marquis reacts on a lot of household products

Sugar / Asprin / Tea etc and they are a great way to check that your kit is still 'active' when you get a new kit test some sugar and note the colour and time of reaction - in 12 months time you can repeat the process and see if you kit is still ok.

Wow. Didn't realise there were so many substances that would give a "black" reaction. Scary.

And yes I do need the Mandelin tester. The last EZ test complete I bought was off and could only find the Marquis reagent.

When testing with sugar is it white sugar or brown sugar? Does it matter?
 
I guess I can use my test kit to test other random house hold items like tea, cause there certainly isn't anything illicit worth testing still!
 
It really is a shame that Australia is not like the Netherlands in respect to the ability to have ones drugs tested for substance(s), and I am fairly sure potency, as this would likely of reduced the shitty 'E' scene we have had for a few years, aswell as being an invaluable resource to 'ecstasy' users regardless of the current state of the scene. There has long been tester foolers but you don't get this with GC/MS and regardless of the general drug users knowledge I think that dealers may of had trouble pushing some of the shitty pills they have got away with if these safeguards had been in place.

It's rather saddening that the only real HR tool available to the intelligent user is a reagent kit that more often than not can be and is faultered by false ingredients these days, the pill market in general seems to be headed in a positive direction at this point in time but only time will tell if this trend will continue. It is definately wise to own a pill testing reagent but even then you should take your results with a grain of salt and dose conservatively, particularly if there is a lack of collective information to confirm the pills contents.

According to Erowid Marquis reagent shows a dark purple/black reaction to atleast DXM or opiates as well as MDxx compounds, I don't imagine too many opiates are pressed into ecstasy pills (although I am sure it is possible) but DXM seems to be an increasingly common adulterant in pills and it is quite scary since the combination of DXM and MDMA can lead to serotonin syndrome that DXM could actually convince a conscienscious user who tests their pills that DXM containing pills are safe to take.

Hey DM, DXM does not turn purple ---> black. It is generally a slow reaction that appears grey and smokey then turns to a charcoal black colour, very distinctive from MDMA.
 
^ thanks for correcting me, I wasn't speaking from experience but rather looked it up and according to here DXM turns black, it does say it is possible to distinguish based on the reaction time but it doesn't really elaborate on that. For some reason I assumed there would be a bit more difficulty than there actually is and that particularly those new to reagent testing may be fooled.
