are all silica gel packets reuseable? and, if they aren’t specifically labelled ‘color indicating’, how can you tell when they’re saturated? Also, do you leave them in their packets for recharging in an oven or microwave, or do you take the beads out of the packets? In advance, many thanks.

It really depends what are you using them for and how much the performance matters to you. I am maintaining a set of astronomical cameras that are cooled to -40 degrees and located around the world – yes, my silicagel is color-indicating, but I still refresh it at any time I am able to physically visit the sites, because the color changes are not very reliable in indicating the progress of the saturation. But this is spending dollars to prevent spending thousands – in a less sensitive application, you can just play it more by ear – or get at least some color-changing pearls and drop them in with the rest for rough indication.
