Unlike natural tektites, Josh's Tektites aren't formed in a vacuum but instead in a studio full of life and creativity. And although they didn't arrive here from the heavens, they are made of same elements as glass meteorites. Josh - still working solo in the hotshop - has now made new Tektites (not antiquities yet), and they are voluptuous.
The four photos below show the changing color of one Tektite as it cools from molten, to red hot, to just very hot, all while still on the pipe. Note the dramatically different Corona glass color in the same piece at room temperature, in the photo just above.
