Tough Tarbell Trivia

[Rob Wick]

This is one of those questions that I am just going to give the answer because I can't think of any other clues. The answer is the lead plates were being melted down to make cores for bullets. What makes this significant (at least to me) is that for a number of years in her early life Tarbell was a strong advocate for peace, however she wasn't upset that her work was symbolically being used for war. To be sure, this came after the Japanese attack on Pearl Harbor, but it still seems ironic to me.
