Looked like cubed brown sugar. Anyways, he took a small amount and only had marquis test in hand. The test was VERY QUICK! he video record it and watched it many times and from what he can tell, it wants to start out as brownish but quickly turns VERY VERY dark almost black and continues to go very black and has a blueish purple hue tint on outside but its so black, he can't really tell. Also it fizzes pretty violently for the 3-4 seconds as it turns color. All of this happens within 4 seconds. He tried searching results like mine but couldn't find one.
If he had to slow it down. The color is like instant yellowish brown to black within .1 second and as it goes to 2-3 seconds, its already very black and bubbling. No vapors.
