I don't recall much about this at all.

A friend, who had recommended many other books/authors I ended up liking, told me about a story in which a scientist develops some kind of special glass, that had some property like slowing down light by a factor of a trillion, or something else odd like that, adventure ensuing.

He's since moved away, and now I'm wondering what this book might have been.

    Perhaps Bob Shaw's slow glass? en.wikipedia.org/wiki/Bob_Shaw . Do you remember anything about the age of the book?

  • @Tony Meyer - well, since most of the other things this guy recommended were 1950's-1970's, I'd hazard to guess somewhere in that time frame.

Yes, that's certainly Bob Shaw's Slow Glass stories (1966), starting with “Light of Other Days” and collected in Other Days, Other Eyes.

  • yep. now I see the blurb on the other side of @Tony Meyer's link, I am sure of it. I misremembered, of course. It wasn't just that light takes a million years to get through, it was that you could make windows into the past.
