    Does that mean acid free paper would last longer?

    I might be worse than paper. It can rot away within a decade or two based on what I've seen in some cases, and it would be difficult to get a good bond between the aluminum and the emulsion. It's just too fragile. I'd be more inclined to use a stainless steel plate with some good thickness (1/8 inch, maybe). But I still think stone is the most feasible way to go, balancing cost with longevity.

    The issue with stone is the size. Limeted space in the time capsule you know.

    What about glass?

    Think about the antique objects of about 10,000 years old. What are they generally made of?

    May be Cyanotype on gold foil.

    How did you sensitize the area on the sidewalk? And did you coat it afterward? Or was it exposed to foot traffic?

    Like Nicholas said, ceramic would be a pretty good bet. Gold.... always a good choice. Glass, I don't see why not. Some might even say that a high-grade plastic would be up the challenge, like polyethylene, and that could be rolled up.

    But, is cyanotype really the longest lived photo artifact out there? Platinum/palladium might be better, or even carbon.

    By the way, are you actually going to be putting this in a time capsule?? That's awesome...
