What Are Those Tiny Beads in Broken Glass?

So, Why Do We Call It Desiccant in Windows?

To clarify, dual-pane windows are sealed to improve insulation. Over time, moisture can leak in to the cavity in between the window panes, vie the eroded seals. The desiccant beads absorb that moisture settling flat against the diffused panel glass.

Common desiccants are:

  • Silica gel
  • Zeolite
  • Molecular sieves

The beads are non-toxic but should be cleaned up so children or pets do not ingest them accidentally.

A Small Mystery Solved

The beads were simply a part of the window construction. They were not a sign looking for action, nor a sign seeking the original burglar. They were just a reminder that even building materials can surprise us.

If you ever see tiny beads alongside broken glass, you are probably looking at the desiccant of a broken dual-pane window.

And of course, if you are in central California and you see someone peddling a lot of suspicious looking Ray-Ban or Costa sunglasses, be sure to reach out!
