Silica Gel & Desiccants

You could always remove the gel from the packets, and put them in something again once you've heated them. Silica shouldn't melt until it gets over 400 F, similar to silicone baking/cooking stuff (since it's all the same thing, silica); not only that but it'll never decompose (unless the temperature exceeds 400).

Thanks for the info everyone. Good to know that I can reuse those little packs and not have to worry about moisture leaking from them. I thought I had read in a different thread that moisture could leak out. I figured the silica would be safe to put in the oven but wasn't sure about the packaging since it isn't metal. Knowing that it has been done before makes me feel more comfortable trying it if I choose to.

This past weekend I decided to recharge my Silica packs. I remembered this thread and how I was informed it is possible to dehydrate the small packs that come in shoe boxes, so I decided to give it a try.

I have 2 small packs that I just recently got (the wife got some shoes) and I put them in with my reusable Silica packs. Set the oven for 300 F and left them in for 3 hours. I didn't have problems with smoke, fire or anything and since the reusable packs show they are good I think it's safe to say the small packs are good also.

Thanks to those who provided information , I've learned that the small Silica packs can be put in the oven without any harm done to them or my house.
