Red, the bottom photo shows there is a pinhole so I don't think this is a warming pour. If it was, I wouldn't expect to see the impression of the plunger on the bottom and it would be a solid piece of glass with a flat bottom, like the left side of this photo: http://www.insulators.info/pictures/?id=11567899 Other warming pours have an excess of glass forming an extra "pedestal" like this example: http://www.insulators.info/pictures/?id=1166660
Now that I think of it, the glass worker would have had to bring the plunger up to temperature too, wouldn't he? Maybe you have some information on how they might have done that?
