Although it is good to claim that all chemicals should be used with great care,
in this case we shouldn't compare apples and oranges. Chrome alum is by far less
toxic than formaldehyde, which has the skull and crossbones symbol (T) on the
bottle. Chrome alum has no danger symbol at all. But the chemists among us
should know better...
