Interesting Small Early Olive Green Black Glass Freeblown Utility Bottle Pontil For Sale

Here we have an interesting utility bottle that dates to sometime between the late 18th Century and the early 19th Century. This bottle was purchased out of a group of bottles that were found by a diver. The bottle has a cylinder form with a neck that gradually flares out. The base has a large tubular pontil scar left from the blowing process. The glass is quite heavy and thick giving it a black glass appearance however, the olive green coloration can be seen when backlit. This bottle stands 4 1/2\" tall and is in overall great condition without any chips, cracks, open bubbles, pot stone issues, etc. There is some staining / iridescence to the glass from being underwater for many years giving this bottle a great patina! If anyone has any questions, please ask.
