When tested with an XRF instrument this vintage recorder (musical instrument) had the following readings:
This is the reading with the XRF analyzer window focused on the gold of the Yamaha logo:
- Lead (Pb): 6,662+/- 282 ppm
- Cadmium (Cd): 4,737 +/-192 ppm
- Mercury (Hg): 1,572 +/- 107 ppm
This is the reading of the brown plastic alone:
- Lead (Pb): 5,365 +/- 195 ppm
The man who owns this instrument is the exact same age as me. I have a distinct childhood memory of having this very same recorder for 4th grade music class. (And these were going in our mouths! With this crazy high lead level! #Gah!)
Do you remember having this recorder too? If so, please leave a comment with your story.
As always, please let me know if you have any questions.
Thank you for reading and for sharing my posts.
