    You can put them in the oven or microwave to get them blue again. Can't remember how long it will take.

    is it poisonous to heat in in a wok and use it again? can the wok still be used for cooking afterwards?

    are you joking?

    At first I thought you were joking, until I saw you are the thread starter.

    All the microwave/oven does, is to remove the "water" from the silica gel, just use low heat for a period of time, until the silica gel turns back to the original colour...

    AFAIK, silica gel is not poisonous. But don't eat them. You can eat other things like peanuts or chocolate if you hungry .

    no need to do all that.
    can buy ready made ECO made in Taiwan packs very cheap
    these have silica gel inside a plastic case with built in electrical plugs
    when the gel is red with moisture
    just plug into any ac outlet for about 5 hours
    it will dry out turn blue
    you can return it to the container with photo stuff
    disadvantage is you cannot control exact RH% as in a dry box

    still intact? of course!

    50 generations down, see whether still intact.

    Hi all, I tried to dry my silica gel with a small frying pan on the stove on low fire...it did turn into a purplish hue from original pink but 80% of the gel turned milky white! Anybody come across this and is it still reusable? thanks!

    I was pondering about that.. I normally get some silica gel in my camera bag when I travel.. Instead of heating in the oven or frying it, can I put it into the dry-cabi to recycle? Does it really work?
