recently i came across a museum specimen placed inside a box with these small clear-yellowish beads. at first i thought they were just some polymer bead that allowed the specimen to sit well with equal pressure on all sides. someone else said that the beads are probably silica gel. is there any test i can do to determine if the beads are silica gel? also they said to throw them out because since they are yellow they aren't "good" anymore? Is this correct or can they be subjected to high heat and be "revived" to be used as a dessicant again? Are they reactive towards other materials? I have noticed that silica gel is usually in bags or contained and kept seperate from other materials.
