Another detail of the beads and a photo showing the ammonia-dampened swabs used to test the red material. The swab used to test a bead in on the bottom and the swab used to test the red portion of the clasp is on the top. The color on the swabs looks a little redder in the photos than it actually is. I should mention that there's still "dirt" in the crevices of the beads and I think that's what's showing up on the Q-Tips.
I'm thinking the beads are not phenalic resin but another type of plastic.
