This one is on the chart of the nucleotides... irradiated Pyrex CD 128, with the threaded skirt. Bought online, "originated" from an antique store near Jacksonville, Florida. Seen one other offered by same seller, listed as 'Amber Pyrex Insulator'.

Color is somewhere in between a 'Peach caught in a fire', and 'Smokey Quartz'. It's like a car wreck; you shouldn't be staring, yet you can't take your eyes off of it.
