mirrors: will one start a fire?

I have been wondering this. We have many clear hot blue days in summer. Will a mirror on the fence start a fire? Has this ever happened to anyone?

    I've had two mirrors out back, both in direct sun.
    I've never had a fire but I will tell you that the plants I had right up against the mirror turned into crispy critters.

    Something about the sun rays bouncing back on the flowers and leaves and burning them to death.

    Maybe use nylon rope or heavy twine on the back of the mirror to sort of tilt the mirror downward when hanging it so it's not getting direct sun?
    I dunno--but I hope someone comes here with an answer about it being a fire hazard. I'd like to know too.

    I haven't been here for awhile, but will add my two cents ......Yes, you can start a fire with the mirror and sun, but you need to have it angled right and in lots of dead grass or other fire starter stuff. Think we used to use the top of a flashlight so it reflected. I wouldn't worry about on tope of a post.

    This reminded me of a caution re a fish bowl in house that sunlight was shining though, almost set some paper near it on fire, started smoldering ( you should never put fish bowl in direct sunlight anyway) Didn't happen to me. Do you suppose that could happen with ornamental glass outside too?

    you know i got to wondering if maybe fish & chips from the other post got too hot in that jar? maybe they didn't have the brains to dive lower....

    Coming out from the lurking rafters....two years ago was a hot sunny day & DH was looking at some stuff at a garage sale . He wasn't standing at the table very long when all of a sudden his shirt caught fire. The gal had a mirror on table & it was reflecting on his shirt it first started smoking and then caught fire. This happened in less than two minutes.

    It was a very scary situation to say the least. Thank goodness it wasn't a small child standing there.
    I have some nice round mirror tiles that I'd love to hang from tree but once was enough for me.
    When we had a sale last year I made sure there were no mirrors.

    I haven't had a problem with my mirrors in the garden. I thought as a kid it was hard to start a fire with a magnifying glass so I am not sure how easy it would be to start one with a mirror. Might be a good experiment(-:

    YES I had a bathroom mirror siting on my dresser that was on the opposite side of the room from the window and the mirror rays sat a pair of gloves on fire. THANK GOD we were home at the time. BE VERY CAREFUL with mirrors.

    I have been considering making a garden mirror along the lines of one I saw on this Uk website but am now having second thoughts after reading these posts.
    Anyway here is the website with a picture of the mirror.

    Sorry. I don't know how to post just the picture.

    Magnifying mirrors definitely will concentrate the sun's rays and start a fire just like a magnifying glass.

    We had this happen in our bathroom - set a roll of paper towels on fire.

    I suspect the other fire stories were related to magnifying mirrors.

    The light needs to be not only reflected, but also refracted in such a way that the hottest part of the spectrum is focused on dry fuel, and has sufficient air flow to breathe life into the fire. Be careful where you put your mirrors in relation to the sun, and then where the focal point of the reflected light falls.

    The cause of my house fire that killed 2 people was determined to be the glass bottles on a window sill reflecting light onto papers that caught fire, then fell behind a dresser.
