A chemist friend of mine said he thought it is some sort of fermentation jug, specifically a 'bioreactor'. Anyway, here is another photo- you can just see the iron pontil mark on the bottom and a glass nipple on the top center (pontil?). I've browsed the web for similar labware but found nothing...
I aquired this recently. Found in a rural area. Does anyone know what it is? I suspect it is some sort of labware. It is free blown with applied lips. It has an iron pontil on the bottom and another pontil in the center of the top. No bubbles in glass. Any help is appreciated. [8D]
