I stumbled across an interesting video of what appears to be gold precipitating in the form of fine shiny leaf-like particles. Please ignore the fact it has an alchemical taste... I know alchemy isn't real... don't need a lecture about it. What I would like is a possible chemical explanation for this apparent precipitation. I've never seen gold precipitate as a shiny golden metal. After some research it seems ethanol has been used in the past to precipitate ultra fine shiny golden particles (isn't there a risk of producing explosives when introducing ethanol to gold solutions?). I've also never seen gold precipitate at the surface of a solution...it seems that contact with air might be catalyzing the reaction? What are your thoughts?
