    Any chemical should be neutralized before "dumping" unconsciously
    into our nations or planet's waterways. Attitudes like this are a
    large percentage of the problem with the planet's impending and
    deteriorating environmental state due to humans and their disregard
    for producing and dumping chemicals, etc. While some forms of copper
    sulfate are used for instance for spraying roses to prevent black
    spot and other viral infections, there are clear and present
    cautions on the packaging put there to inform users and regarding the
    safe disposal of the packaging and unused solution in- for instance-
    the tank sprayer used in rose care.. 

    However, Sulfuric acid is NEVER safer than Sodium Bisulphate.
    Particularly if one has to prepare a 10% solution from virgin acid-
    buffered or not out of the bottle, it is always more hazardous than
    anhydrous chemicals (pHdown or sodium bisulphate)..and while touting
    the use of sulphuric acid I do not see any instruction you give for
    its safe handling or proper disposal. It seems if you intend to
    educate new jewelers with your vast and voluminous "knowledge",
    concern for their safety, and the safety of our shared planet as
    regards jewelers chemicals should be de rigeuer when proposing any
    chemical for the small studio as used by beginners often having no
    education but learning as they go, by trial-and-error, particularly
    given the large margin for error chemical hazards present in the
    home, in the studio and in the school.
