What antique bottle collector doesn't love a colored pontiled antique soda bottle.  There are none!  This pair of early squat east coast soda bottles sparkle like the day they were discarded after a light cleaning by the glass artisan.  Notice both have iron pontils.  Cleaning pontiled bottles requires the pontil to be protected.  The Glass Artisan removes a super fine later of sick glass when cleaning while leaving every spec of iron in the pontil.
