conchoidal fracture

Thank you Adam
Yes that seems to be it alright
A conchoidal fracture has curved lines, rather like a sea-shell (which is where the word "conchoidal" comes from). Obsidian has conchoidal fractures, as does ordinary glass.

I'm glad it translates easily into German for you Pamela  :)

obsidian is glass 8)
Die Erfahrung lehrt, dass, wer auf irgendeinem Gebiet zu sammeln anfängt, eine Wandlung in seiner Seele anheben spürt. Er wird ein freudiger Mensch, den eine tiefere Teilnahme erfüllt, und ein offeneres Verständnis für die Dinge dieser Welt bewegt seine Seele.
Experience teaches that anyone who begins to collect in any field can feel a change in his soul. He becomes a joyful man filled with a deeper empathy, and a more open understanding moves his soul.
Alfred Lichtwark (1852-1914)
