<p>[QUOTE=&quot;springfld.arsenal, post: 99683, member: 54&quot;]I&#039;m pretty sure y&#039;all know it isn&#039;t natural obsidian but a cast substitute which may or may not contain ground-up obsidian.&nbsp; The castable substitutes are often used to make obelisk-shaped large crystals, pagodas, etc. for souvenir vendors.&nbsp; Natural obsidian is natural glass and can be chipped into arrowheads etc. but can&#039;t be carved economically into shapes like the head pictured above.&nbsp; Think of trying to carve flint figurines and why flint is chipped or knapped to make weapons-obsidian is very similar.[/QUOTE]</p><p><br /></p>
