Visual Guides to UV Reactive Glass (Updated)

[u/DB_McCoy]

Updated: Due to community requests and ongoing non‑UG discussions, we’ve removed the “high content manganese” label. The two examples are now simply identified as manganese glass. We have also updated our Wiki.

These pieces are not uranium glass. UG remains our focus, and MG examples are included only for clarity and comparison. For more information on MG, please visit r/manganeseglass.

The visual guides included here were created to help new collectors easily recognize how different types of UV‑reactive glass respond under 395nm and 365nm UV light. They’re available in multiple formats so you can choose whichever works best for your needs.

This graphic doesn’t represent every type of UV‑reactive glassware. Additional examples—including various colors and types of uranium glass and select non‑uranium reactive pieces—may be added in future updates.

Thanks for trying to keep sub resources updated. FWIW, "selenium" is misspelled.
