Just curious.

Anything else that responds black to marquis?

This shows the reaction at the bottom. DXM does a slow brown to black, versus the quick purple/black of MDMA.
I just pulled out my kit that is over a year old, has a slight leak and is a slight brownish color. I had a tiny crystal stuck in my stash box that turned black and bubbled. I hear it is only good for a year but mine reacts.

MDA, MDEA, MDMA, DXM
but Propoxyphene turns dark purple, Morphine turns a deep red/purple, Doxepin dark black/red, Codeine very dark purple....

So how long will one last?
It depends. I have had a test kit that tested accurately for 2 years and one that went bad after 6 months. Unfortunately you really have no way of knowing how long the bottle has been sitting around in the warehouse.

Usually the instruction says if there is a colour change in the tester when nothing is added to it

2. Quality Check:
Marquis Reagent (E: a quick and simple test) is more susceptible to ‘going off’. The testers’ quality/suitability can be verified by checking its reaction with aspirin. Scrape a small amount of aspirin, much like a test with a ‘pill’, and add a drop of reagent. The reaction generated should be a bright red/cherry colour developing within about 5 to 10 seconds (a slow reaction). A reaction too much slower than this indicates that the reagent has lost its activity. In addition, check the colour of the solution coming out of the bottle. It should be clear and colourless. Over time, the reagent will develop a light brown colour. Once the reagent has become a colour similar to a light ‘beer’ shade, it is near the end of its useful life.
Mandelin Reagent (E2: 2nd Defence) is normally a clear, orange/yellow solution. Over time, it develops a yellow precipitate, and turns green. Once the yellow colour has left the solution, the reagent is past its useful life. The testers’ quality/suitability can be verified by checking its reaction with one of two common household products. Test ‘a’ is the preferred method, as it is a stronger reaction:
a. Asprin – Scrape a small amount of asprin from a pure tablet, much like a test with a ‘pill’, and add a drop of reagent. The reaction generated should be a strong Olive Green.
b. Acetaminophen (Paracetamol) - Scrape a small amount of acetaminophen from a pure tablet, much like a test with a ‘pill’, and add a drop of reagent. The reaction generated should be a weak olive/green colour developing.
If either one of these reaction are not present, the tester has lost its activity, and is at the end of its useful life.
from chemicalgeneration, they make E1 and E2 (marquis and mandelin)
