I get the spelling of whetting from "American Glass", George and Helen Mckearin, page 24, illustration 13.I think the term is "wetted off," not "whetted off." I believe the term derives from the dipping of the shears in water to chill them before touching them to the neck of the nascent bottle. Thermal shock is what separates the bottle from the pontil rod.
