How do you make a bologna bottle?

  1. May 15, 2007 #1
    A bologna bottle is a glass bottle that is hard enough to pound nails with, but if the inside is scratched the bottle shatters.
    I know that the bottle is made by cooling the outside slowly and the inside quickly, but is this something anyone can do? how slowly does the outside have to cool and how quickly for the inside? can a coke bottle be turned into a bologna bottle?
