Lee W. Posted July 11, 2022 Share Posted July 11, 2022 This does not react with white vinegar, however I am concerned about putting copper ore into the tank. I am not even sure it is water soluble. It is small and kinda cool looking plus it has some sentimental value. The pieces pictured are NOT mine but closely represent what I have. Does anyone know more about this?
