[SEL] Creating Antique Patina - Reverse Electrolysis

[John Culp]

This is interesting, because in recent days I've learned on the Tube 
Collectors Association mailing list that the tube manufacturers learned 
from experience that they had to ban women at certain times of the 
month from working with the fine iron wire used in barretter or 
"ballast" tubes. Their perspiration was too corrosive. Another member 
reported that AWA in Australia encountered the same problem with the 
fine wire in wireless coils. Another wondered if that meant that ALL 
the women in the plant eventually got a monthly holiday due to the 
common phenomenon of cycle synchronization.
