Methamphetamine contains phosphorus, which can glow under ultraviolet light like a black light due to the presence of fluorescent impurities in the crystal structure. This phenomenon is sometimes used by law enforcement to detect the presence of methamphetamine residue during investigations.
When a crystal of copper sulfate is strongly heated, it undergoes dehydration and turns into anhydrous copper sulfate, leaving a white residue. This white residue is the anhydrous form of copper sulfate, which has lost its water molecules during the heating process.

One can purchase a black crystal chandelier on eBay for $155.03 to $750. One can also purchase one on "Light in the Box", "Black-Chandelier" or "Houzz".

Lead residue is typically grayish or black in color.
Black residue on a black candle could indicate incomplete burning, poor quality candle wax, or impurities in the wax. It could also be due to the candle being exposed to drafts, causing uneven burning and residue.
is there a lot of potassium in crystal light
The oily residue was sent to the lab for examination.Go and wash that residue off your hands.
Incomplete combustion of carbon-containing compounds, such as hydrocarbons, can lead to the formation of black residue due to the production of elemental carbon (soot). This soot is responsible for the black color seen in the residue.
