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?:bsmilie:

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 :bsmilie: .

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

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?
