Can you put these packs in the oven to re-activate them?

Yes. I believe the directions are something like 220 for 2 hours. I personally put them into a food dehydrator for 2 hours at 165. I have some other kinds which have indicator crystals so you can tell when they are recharged and I do them all in one batch. So far, 2 hours at 165 seems to work just fine. If you have them in an oven, do keep an eye on them so the paper doesn't scorch.

I think you could put them on a cookie sheet and put that in the oven. There is a rack to cook the pizza on in the oven

Yes but I wouldn't recommend holding anything with them, and if you do don't hold don't them for a long period of time, the reason why I say this because I tested them out to see how long they can last, so I took a pan out of the oven around 350° and they only were able to last around 10 second, unless you double fold them.

Yes! It took me a little while to air out the kitchen and I was kind of sorry I put them in my new oven. They didn't smell afterward though, but you still can't eat out of them, and I wouldn't wash them.

You can! These packs will accept either, "rollies" or store bought packs. Thats why I gave them 5 stars!

The packs are the heating element. You can use them until they get damaged. Just make sure to follow the instructions so you do not over heat them. I have not had any issues with mine.

You can use them over and over again... You just need to watch out for the time you put them in the microwave, if you are using them warm... I put mine for too long and one actually explodes :-(... They are a great product, just follow the instructions!

The are one time use, however... I have found that I can wear them in my leather gloves during the morning drive, then wrap my glove tightly with the warmer inside and put it in my pocket... 9 hours later, I still have some heat left for the drive home. The key is limiting the oxygen exposure. I suspect that if I were to put the previously opened packs in a plastic bag while I'm at work, they'd be even warmer for the drive home.

Hi Michael, Yes indeed you may leave them in the oven while you are self cleaning. In fact, that's one of the ways we recommend you clean them. These are designed to take all the heat you can dish out and then some so don't worry. Thank you for your business.(Dough) Joe

Though, I haven't ever done it, I definitely think you can. These baking sheets are wonderful and they last and last. I bake quite frequently and have been using the same ones I originally ordered for almost 2 years.

I would not put them in the oven. They are good to use in the microwave, however. Just leave the plastic lid off.

Silica Gel has no experation date. In fact, if Silica Gel draws enough moisture, you can put the packs in the oven at about 120F degrees. I was in the Military for 27 years and this is how we were able to dry them out for reuse.

I've never tried it, but I don't see why you couldn't. Also - they come with paper cup liners inside each foil cut, so you could replace those with the colored paper cups and remove the foil ones after baking.

Yes you can cook them and let them air dry to be crunchy or let them cook less time and they will be a little more chewy.

I doubt it. They are plastic. I haven't and wouldn't even try it. I have put them in the microwave. But I avoid microwaves as much as possible myself. Just my preference on reheating food.
