## Emergence
**Emerges from:** [material](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-material.physical), [structure](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-structure.arrangement), [transparent](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-transparent.visual)

**Through:** the material has an arrangement that enables transparency.

**Novel properties:**
- transparency
- rigid, non-crystalline structure

## Examples
- The Corning Museum of Glass displays a 2,000-year-old Roman glass cup that still transmits light clearly. *(archaeology)*
- Fiber-optic cables in the MAREA transatlantic system use ultra-pure glass to transmit data with minimal signal loss. *(engineering)*
- The glass panes in the Louvre Pyramid remain transparent after decades of exposure to Parisian rain and pollution. *(architecture)*
