The microwave forces the water out of the desiccant but it’s on the surface. The oven dries them out completely. To test when they can be taken pit of the oven, take some desiccant out and put a cool glass over them: if moisture condenses on the inside of the glass then keep them in the oven. When no moisture condenses on the glass they are fully dried out.
I'm thinking of creating a case with transparant windows to showcase a vintage lens. It would also doubles as an air tight box with scilica gel compartment to keep humidity levels low. At the back of the box I would put a digital humidity device to show the status. We must preserve vintage lenses as much as we can. They are only going down in numbers.
I use WiseHIC indicator strips, which change colour based on humidity. They are cheap (about $1 each) don't take up much room, and don't need batteries. 😀
Where they not restored fully after the microwave? And how long did you pop them in the over for afterwards?

Hi! If I don't have an oven and only have a microwave. Is microwaving enough?
Surely
Heya, you can skip the microwave if doing the oven, or vice versa :)
Yes you can but I find microwaving is much faster.
Did the color change? I was expecting it to turn back to blue.
This desiccant is orange when fresh and goes dark green when saturated. There is a different desiccant that uses cobalt for the indicator, it’s blue.
@@VonBromPhoto got it. Thank you.
@@neilfpv and the blue one is toxic.
Well, ya, except burning nat gas produces water, no?
It’s an electric oven.
