In another thread we were discusssing different types of blue when one had no access to Paris Green (which most of us haven't).
Then I found this formula with simply ammonium perchlorate and copper benzoate. If it looks the same IRL as in the video it's amazing.
No, you will need a soluble copper salt. React copper carbonate with acetic acid first, then proceed to react that with potassium benzoate dissolved in distilled water.
The result will be a light blue precipitate which can be seperated in a coffee filter.
