Is there a source in the gemara for "Blei Gissen" (pouring lead)?

A recent article in the 5 Towns Jewish Times claims

Blei gissen, the technique of pouring lead to nullify ayin ha’ra, the poisonous evil eye, has its source in the Gemara ...

In his critique of the article, R' Natan Slifkin points out that the article does not provide said source, and that he has been unable to find it. He goes on to show that there are sources for this practice outside the Gemara, and indeed, outside Judaism - in ancient Greece and in Germany.

R' Yosef Gavriel Bechover also appears to be unaware of a source in the Gemara, suggesting instead, tongue-in-cheek, that "Gemara" must be a typo for "Germany."

So, is there a source for this practice in the Gemara? If so, where?
