Hi,

    Obsidians have hundreds to thousands of times more water in
them than tektites. Heat obsidian in a vacuum and watch it bubble
away like crazy. Tektites basically just sit there when heated;
there's nothing to outgas.
    On the other hand, the furnaces are hard to carry to shows,
there's no 440 V. lines available, etc., etc. But it's a positive
test.
