I didn't find this in the article, so:

You can "recharge" silical gel by baking in the oven at 120 C for a couple of hours. If you do, be careful to remove the casing before you do, unless it is heat safe.

I have a small collection of oven safe dessicant packs that I keep on hand for emergency drying electronics.

Can someone speak authoritatively on how safe/unsafe it is to put the silica gel packets with cobalt chloride indicator into the oven?

(By default, I've been assuming it's not sufficiently safe.)

There's silica gel you can buy without cobalt chloride that I use for storing my 3d print filament.

I also do this. I'm wondering whether anyone needs to be warned about cobalt chloride, or it's innocuous.
