Some fun facts:
- Conservation specialists analyzed the flag's pH to determine the best method for cleaning it (they used dry sponges first, then an acetone solvent and blotting paper).
- A spectrometer was used to analyze colors - including those of stains on the fabric.
- Microscopic images helped determine where the weakest thread fibers were so that the flag could be properly supported.
New Voices tips our hat to the original creators of the flag, lyricist Francis Scott Key, the troops that successfully fought the British that September night, and the scientists and historians working together to preserve American history.
