I think that 1990 is probably pretty close to the point where chemistry sets finally got safe(r).

I was born in the early 80s and my older brother was born in the mid 70s, and I distinctly remember preferring to play with his old hand-me-down chemistry set rather than mine. One like his could not be found in stores anywhere by the time I was old enough to be interested in a chemistry set.

But I also never gave myself any horrible chemical burns playing with my own chemistry set. So it's probably a decent trade-off, all told.
