Obsidian

Glass says that in the US, "obsidian prevention is prohibited by law." Any further information? - Montréalais 08:32, 24 Dec 2004 (UTC)

"obsidian collection is prohibited...". I'm intrigued, too. EdDavies 22:49, 23 September 2005 (UTC)[reply]

I believe it's only the taking of obsidian artifacts from national parks and archaeological sites that's actually illegal. SamEV 08:22, 31 October 2005 (UTC)[reply]

Yes, that seems to make a lot more sense. I'll put a note on Talk:Glass about it. EdDavies 22:58, 17 November 2005 (UTC)[reply]

large piece of Obsidian

I have a large piece of Obsidian, I think its very unusal to find this type in the area that I live (Kitchener, Ontario Canada). If anyone out there has any information on Obsidian and where it is usually found I would be quite interested to hear.

Thanks (Curious)

I would guess that it was eroded out of its primary deposit and carried along with a glacier. Then when the glacier receded, it dropped out. Ask your local university about moraines in your area. Woland37 18:29, 30 November 2006 (UTC)[reply]

Comment

Nice start to an article, but very biased towards the US and MesoAmerica (probably because the writers know those areas best). There's nothing on the amazing Palaeolithic, Epipalaeolithic and Neolithic obsidian tools from the Middle East, especially Iraq? I saw some fantastic long obsidian blades and blade cores in Mosul Museum in Iraq in 1989, but suspect they have long since been bombed or smashed. The Maori used obsidian in New Zealand. There are lots of other locations and cultures where obsidian occurs and has been utilised - anyone with more information able to expand? 81.159.88.164 (talk) 15:42, 11 March 2008 (UTC)[reply]

Furthermore...

Another interesting you could post about minerals is how to cut and shape them. I have a friend who tried to cut obsidian on his own with a hammer and a chisel and ended up slicing himself something nasty. Knowing how to home shape a mineral or at least a warning not to could be useful to some. ~~Mr. Wonderful~~

Mr Wonderful: Your friend is an idiot. Obsidian fractures with ==EXTREMELY== sharp edges. Obsidian has been / is used by surgeons due to its potential for an extremely sharp edge. It is much sharper than man-made steel blades, and should not be worked except by those that understand the danger involved. If interested in working siliceous rock, do some research on flintknapping.

Metallic obsidian?

Is there really a natural material called "metallic obsidian" as shown in one image? If not the image should be removed. Wilson44691 (talk) 22:19, 31 July 2008 (UTC)[reply]
