This is a query for those of you who know people who have come across different RC's. In a perfect world, RC's would be 100% pure and their appearance would correspond exactly with the description in pikal/<st1:City><st1lace>tikal</st1lace></st1:City>. Is this the case with RC's you have seen? Trying to be as specific as possible in terms of colour, consistency (clumped, powdery etc), homogeneity (a single pure substance, or something different distinct parts) etc. Hotlinking to a picture of an Research Chemical would be ideal for those of you with digital cameras. (you can host images @ imageshack.us) Remember, if you're taking a picture of a light coloured substance, a dark background will give the best results. <br style=""> Why am I so interested? A friend of mine recently came across a couple of RC's that didn't quite meet what he expected in terms of their physical appearance. He compared them to only one or two pictures hosted on Erowid, and was unable to find any other pictures around the net. It is possible that there is a variation in physical appearance within a reasonably pure substance depending on how it was prepared. Perhaps some RC’s are sold with “filler” chemicals to bulk them up. So let me start off with my friends description of a couple RC's he happened across: <b style="">2-CI[/b] This sample was pure white and sparkly. It did not bunch into larger clumps. In fact, it was a consistent sample of very fine "crystal bristles" ranging from near powder to 1mm in length. <b style="">5-Meo-Dipt[/b] This sample was off white - pinkish or orangeish. Much of the sample was made up of .5mm "flakes". As the bag was tilted, these flakes sparkled each in turn. This sample contained many irregular clumps. Oddly, it also had in it larger pink/brown crystal chunks that seemed to be distinctly different from the bulk of the material. This sample was on sale – perhaps it was the last of a large batch. Anyone else have some descriptions or photos of stuff they or their friends may have seen?
