Cut 'em open and pour them in a jar with a tight seal. When you need a pack, microwave hell out of some and rubber band them into a piece of coffee filter.

The colored beads indicate how water saturated they are. When they're nuked and dried out, they change color. YMMV as some manufacturers use different colors or none at all. Whatever. Nuke 'em and reuse.

It's an exciting hobby.

In any case, silica does not need to get near the melting point to lose it's ability to adsorb water. Best to help it below 150 °C to not damage the microstructure.
