Where I live, there are pyro milk bottles worth thousands. However, by the time I dig them up, the enamel coloring is either gone or quickly fades once hit by the light of day. Interestingly, there is always what seems to be an acid-etched after-image. It would seem this ghostly template could be used for reapplying pyro-glaze color, though I once read the process has been lost to time. The question arises: Is the afterimage retained by milk bottles upon losing their color the result of enamel effecting/etching the glass or does the pyro-glazing process involve first etching the glass so the enamel only sticks to that area? Any thoughts. The fist person come up with re-glazing process could have one heck of a pyro milk bottle collection.
