RE: [Histonet] E.M. precipitate
Lead is often the culprit in forming precipitates. Several different lead stains are in use. Reynolds lead citrate is the one I prefer. I make it up fresh weekly. I also place several pellets of sodium hydroxide in the staining dish to absorb atmospheric CO2 which can react with the stain to form insoluble lead carbonate.
