- williamscales 1y agoI don't see any method for lead chromate in turmeric powder, unless I'm missing something.
- gitaarik 1y agoIt's used for coloring, because it makes it apparently gives it the same color as good real tumeric
- williamscales 1y agoOK, so the method given for artificial coloring on that page. I'm curious if that works for lead chromate. It seems so simple that it must have been tried in this case? Regardless I'll file it away to at least try on stuff to avoid what colors it can detect.
- thaumasiotes 1y agoIt's the one below the one ashwinsundar linked, "detection of artificial colour in turmeric powder". The test is: when you add the powdered turmeric to water, natural turmeric will give the water a "light" yellow color, while adulterated turmeric will give it a "strong" yellow color. This is not a test that I'd characterize as "easy" or "reliable".

- account42 1y agoYeah, I wouldn't trust this test without a reference sample for comparison.
- gitaarik 1y agoYes indeed. Here's also an instruction video for it: https://www.youtube.com/watch?v=tXWPf0HQd5U https://www.youtube.com/watch?v=tXWPf0HQd5U
- wahnfrieden 1y ago> Lead Chromate apparently has an extremely low solubility in water, so how does this work?
