Hi and welcome.

I can't help with your glass, but I'm afraid we'll have to ask you to change your username if you still can.
It is purely to prevent your email address from getting harvested by spambots.

I'll contact a moderator in case they are needed to help you do this.
Somebody else will know about your glass, don't worry - it's just not my area, although I do not think this shape is correct for a ship's decanter. They have wide flat bottoms so they don't fall over on high seas.
