VERY IMPT. INFORMATION TO NEW PIPE GUYS !!
DO NOT store pipes with vulcanite mouth pieces in Daylight(pipe racks or any where).. Daylight causes severe oxidation of the vulcanite mouth pieces and turns them GREEN. This oxidation, if severe is very very difficult or impossible to polish or even buff off. I think it also gives the mouth piece a terrible taste.
Store your pipes out of daylight as in drawers or closests. For me this makes Pipe display racks a no-no.
Interestingly enough, most of the older and highly expensive pipes(Dunhill, Charatan,Comoy,) were made exclusively with the rubber-base vulcanite mouth pieces at least through the 90s. The more modern
American, Italian, and Danish pipes are made often with Lucite which is harder, a little thicker, and doesnt turn GREEN when left out in the light. My god there is nothing uglier than a beautiful old high value estate pipe with a dull vomit green mouth piece and they are very very difficult to clean and buffing can obliterate other significant pipe markings. Also if the Pipe looks dull green one can anticipate a sour smoke.
