Hi All, I have an unusual question for the group: what happens to a tektite when you heat it up to its melting point and then let it cool back down? Aside from any plastic changes in the shape, are there any color effects? I wouldn't have thought so, but I've been told of cases of "heat-treating" tektites to drastically alter their color, and I wondered if it was a bunch of baloney. --Rob
