Well I am sorry you and or others find my tone "hostile and offensive". Quite why that is goes over my head it would seem.
Yes it was me who described it as an Ink Bottle but have now asked that it be treated as a "bottle" so as not to go off on a tangent over what function it was made for as opposed to the question asked which is if anyone knows who made it.
"neither do they find the need to support their knowledge of glass by means of boastful details of their buying and selling."
I was not supporting my knowledge of glass so much as pointing out that whatever a seller says an item is does not always have a bearing on what it actually is. You may note that during my "boost" I also pointed out my own lack of knowledge at times.
