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.

You can buy a microwave kiln set on Amazon, that is how common they are and they easily get above 1000 °C the way you get them. You can also make your own, there are tons of good ideas/designs/tutorials on YouTube.
