Testing to see if a Marquis is still good

I've had my marquis for about 10 months now. I probably only test about one pill a month but it seems like every time the Marquis just gives no reaction. It could just be because of all the pipes around, which wouldn't surprise me, but I don't even get the fizz reaction that people speak about. My Marquis seems to be slightly yellow in colour by default. Is that normal?

Is there some household chemical that can be tested to determine if the Marquis is still good? I heard that aspirin will turn red but I don't happen to have any at the moment.

Also, when I test I take a knife and just take the tiniest scrapings off the middle of the pill. Do you need more, like a good chunk or should dust be sufficient?

I'm not sure about the yellow color, but what you're describing sounds far from normal. Marquis usually only fizzes and smokes (along with going straight to black) when the substance you're testing is PURE MDMA (like molly). There are very few instances where it will give that type of reaction with pressed pills. The most you'll see with pressed pills is a very rapid change to black (if it's the real thing, that is..). Otherwise you'll see other colors, unless, as you suggested, the pills you've been testing have all been BZP/TFMPP/DBZP/random piperazine presses.

There are no household chemicals I know of that can be used to determine the potency/activity of your Marquis reagent. The aspirin color change is something I've not heard of.

As far as the amount of the pill needed to test, a small scraping is sufficient. The general rule of thumb is: If you can see it on the plate, it's enough. A chunk is too much.

One of the problems you might run into with pills these days are how the ingredient(s) are distributed throughout the pill. There have been many instances during testing where I've discovered that one side tests differently than the other, and scrapings from the middle (breaking in half, and then scraping) test differently. If you haven't tried this yet, I recommend keeping it in mind the next time you test. No two presses are alike, unless they're from the same batch (and even then, some aren't).

My test kit is about 13 months old been kept in the fridge etc.

The marquis is off im pretty sure because it takes an extremely long time to go to black (Like 40 seconds) when it used to do it instantly on the same pills plus mecke and mandelin go straight away
