GUDERIAN GLASS
[ 5.9.2026 ] Polymer handling notes
One of my videos shows a red dyed polymer bead cut into pieces. Breaking the spherical polymer into fractional shapes helps create a scaffolding upon which the glass shards will rest instead of passing through. Intact polymer spheres naturally create a honeycomb pattern. Gaps form between the spheres, and glass can fall through these gaps in ways that are undesirable.
I have found that maintaining a ratio around 3:1 intact to broken polymer keeps the glass in place. Large sections of intact polymer not only allow small shards to pass through, they can also fail to keep larger shards in place. After sealing a jar I will stress test it by shaking and rotating vigorously. This exposes air bubbles and reveals unstable regions of polymer that needs to be broken up.
