Adorama Reusable Silica Gel

I have had these Adorama Reusable Silica Gel in aluminum containers for a long time, I have 3 of them that I've kept for almost 3 years now. It takes about 3-4 days for them to hydrate before I have to de-hydrate them again. I usually put them in the oven at 300 F for 30 minutes before they turn extremely dark blue, almost black. I see that the instruction says bake them for 3 hours. However it is dark blue within 30 minutes and lasts for 3-4 days. Have anybody here tried baking them for an actual 3 hours? Are the colors different than what I've described and do they last longer? Such as a week at least?

Silica Gel

I have these also about 9 of them. I always bake them for the full 3 hours and they last about a month - 6 weeks in a closed camera bag. I have 2 in my everyday camera bag and the last about 3-4 weeks too.
These Silica packs are also available at Lee Valley tools and on ebay.

I can't tell you whether the colors are accurate or not, but I can tell you that you can't ver-bake" them. The color change is caused by something that can't burn off in a home oven. And as Chris_T said, bake them fully and they'll last longer.
Lee Valley Tools, BTW, has a large canister of them, too. Good for tool boxes or large photo storage case.

Thanks everybody. I baked them for another 30 minutes which is an hour, and the blue color seems more flush, I'm sure if I would've baked it all the way for 3 hours it'll be a brighter blue. Will bake them all the way next time, saves a lot of time not having to bake them every 3-4 days. Sheesh.

A good thing to do with those would be to buy a bunch more than you need and store the extras in some airtight container, until the first ones are expended: then you don't have to heat up the oven for all that time as often. (I use some little things like that and keep meaning to do just the same: nothing says you couldn't recharge them in batches and have that cover you for a lot longer. )

Doesn't regular baking use more energy (both human and utilities) than a cheap electric dry cabinet?

If you're talking about using a dry cabinet to store your equipment, then you're probably right. But, I can't imagine people carrying one on their backs.

Or an oven!

Do people really carry their lenses around in ziplocks with desiccant? Maybe I'm being reckless!

I use this company for my silica gel packs. You can bulk buy their aluminum containers for a cheaper price than Adorama.

Not in ziplock bags, but I do have desiccant packs in each of my lens cases/pouches and in my shoulder bag.
