Contest Revealed

Last week I posted this photo as a contest and asked you to correctly identify the mysterious crustiness. Well, there were 14 guesses, and 6 right answers, but Megan was the first! It is nasty, crusty pickle build up. Liquid evaporates fast in Arizona! For those of you non-metalsmiths, pickle is an acidic solution that cleans metal after it has been soldered or heated. I think that was too easy, next time I will make sure to stump you! Megan, e-mail me your address and I will send you your prize! Wasn't that fun?!
