Some advanced pill testing info:
You really do need to be diligent here, and use your experience. For best results, use a fresh tester at room temperature. Take your scraping, and spead it out to be about 0.7cm in diammeter (approx 1 drop of liquid in size). Don't totally crush it to smitherines, just let it break into it's 'natural' bits.
Drop the liquid onto the sample, and look at it under good white lighting immediately. Not too bright, just good white light. Immediately start to swirl the drop around, looking carefully at each fragment, looking for different colours and hues, and for different speeds of change. You can often pick up mixtures by the miniscule colour variants seen. This is particularly apparent with 're-engineered' pills. The swirling also 'thins' the liquid layer you are looking at, making the colours more easily seen, rather than just seeing a concentrated section of colour that really just looks black from the beginning. WHat I mean is that you look at a thin layer of purple and can see purple, rather than looking at a thick layer of purple, which looks black!
For good MDMA (with good freash tester), you WILL see a dark royal blue at the start, followed by a dark purple, and then the black will kick in within probably a few seconds, but sections should remain blue/purple for around 30 seconds or so. The blues and purples should be visible clearly if you SWIRL!
Same techniques should be applied to E2: 2nd Defence!
Effervescence is just due to the inert fillers they use. You can use Calcium hydrogen phosphate, perhaps Magnesium Oxide, perhaps Calcium carbonate to 'fill' your pills. Some of these react with the sulphuric acid to product carbon dioxide (usually from calcium carbonate - remember from chemistry: acid + carbonate = salt + water + carbon dioxide).
You can tell the difference between MDA and MDMA with the Marquis Reagent, but the problem is that you need a good fresh tester (which most of you won't have), a keen eye, good technique and lighting, and a sample which is JUST one or the other. It is the latter of all of these which is the most difficult. Pills are full of impurities, starting materials, and other small amounts of crap which also give colour changes and interfere with your result. Spreading the sample and swirling helps, but it is not going to help much.
As for speed, well, I'm not too convinced yet that quiucker reaction equals better pill. I think temperature and age of your tester have more to do with it. I do think that if you are an experienced tester, you can start to get semi-quantitative results from your testers. The intensity of the reaction, in comparison to what you have seen before, can help to provide some information on strength, just not a huge amount! You may start to get an idea about this after doing a number of tests and comparing with the 'test drive'.
A word of caution - A quick black reaction is NOT a desirable thing. I can add inert things to a pill to make it go nice and black very quickly. Look for the DARK BLUE, and the purple.
Hope this helps. More info on our website soon. Any other questions, please contact me and we'll start to post some of these on our FAQ's and forward to Bluelight.
Enjoy.
