[QUOTE="gsimonel, post: 2814704, member: 82549"]The dissolved solids aren't the problem. Much tap water contains chlorine, which, given the right conditions, can trigger the onset of bronze disease. Not always. Sometime you just have a soft green patina that can be scratched or chipped off. Here's an example from my collection: [IMG]http://www.feltemp.com/Images/GoldenAge/MarcusAurelius.JPG[/IMG] Marcus Aurelius Provincial Bronze (AE26) Moesia Inferior, Nikopolis ad Istrum, before A.D. 161 Obv: AVPHΛIOC OVHPOC KAICAP Rev: NEIKOΠOΛEITΩNΠPOC IC - Serapis, standing left, holding scepter and sacrificing with patera over altar. Unlisted in Moushmov or RPC; unpublished? 26mm, 11.0g. The patina is stable, but fragile, and I wouldn't want to take a brass brush to it.[/QUOTE]
