    Acid substitutes work in 99% but not in 100% and it is the last
    percent that always gets you. I was always told that Murphy lives
    under the bench. The safety of handling chemicals cannot be taught
    via email instructions. Anybody who intents to handle chemicals 
should
    go to the local school and spent some time with chemistry teacher.
    But the larger point is that jewellery making is dangerous no matter
    which aspect of it is examined. The solution is not to stop using it,
    but to learn how to do it correctly.
