That is my burning question. Just what the heck is this piece? I have been told a warming pour, but a warm pour is always solid glass, not plunged. Is it a cold pour??? They let the mould get too cold? The piece has been used it seems ~after~ the glass was affected, it still has the rubber left in the WG from when it was on a pole. If it was a sandblasted piece or acid etched, the surface would be almost uniform, this surface has pits, cracks, smooth area, wrinkles and translucent area's both outside and inside. Whatzzit???? If you know, PLEASE email me.
