|To-do list for Obsidian:|
- "obsidian collection is prohibited...". I'm intrigued, too. EdDavies 22:49, 23 September 2005 (UTC)
- 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)
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.
- 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)
- Obsidian is rare, though sizable obsidian (even large boulders) are common at Newberry Volcanic monument in central Oregon. The reason it is rare is because it forms from high-silica lava, must cool quickly before crystals can form, and must be free of volatiles. Also keep in mind that just because a shield volcano may spew low-silica basaltic lava doesn't mean it never has (or ever will) spew high-silica rhyolitic lava, Newberry is an example. If you don't want to drill bore holes I would explore volcanic vents with recent lava flows (particularly short and jagged ones, but there are exceptions, Ring Creek lava flow is one) near glaciers. Mount Garibaldi in British Columbia is a good example having Holocene rhyodacitic lava flows and The Barrier which is a rock wall formed from the collision of lava and glacier. This MINFILE record inspired a few of us to go investigate the area last summer, but it's a good bet that any obsidian is either controlled in a park, owned by a resource company, or buried Exsuscito (talk) 22:32, 15 April 2011 (UTC)
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? 22.214.171.124 (talk) 15:42, 11 March 2008 (UTC)
Obsidian is more than one color. It can be red,brown,black. And in Rainbow Obsidian blue, green, red, orange or yellow. —Preceding unsigned comment added by 126.96.36.199 (talk) 18:52, 30 April 2008 (UTC)

I don't know about the rest of those colours, but green obsidian is found at Pachuca. It's also mentioned in Obsidian use in Mesoamerica. Here's a rather long reference that's a pretty good read if you're into that subject. 184.108.40.206 (talk) 07:27, 10 October 2017 (UTC) https://books.google.ca/books?id=wX4UMndFQgQC&pg=PA223&lpg=PA223&dq=Green+obsidian+-healing+-sell+-sale&source=bl&ots=u_osrwFFYv&sig=26dv8a9IBk9PG1of8r4ja-yP6DE&hl=en&sa=X&ved=0ahUKEwium8GRv-XWAhXBjVQKHaoFBDsQ6AEIsAEwHg#v=onepage&q=Green%20obsidian%20-healing%20-sell%20-sale&f=false
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. —Preceding unsigned comment added by 220.127.116.11 (talk) 02:52, 27 February 2011 (UTC)

Obsidian is a common material in many fictional settings, for example: minecraft and A Song of Ice and Fire, shouldn't this be mentioned in the article?
- It is not, by itself, notable that a real material exists in a fictional setting. (Consider how many settings feature leather and wood.) Moreover, while obsidian may relate to Minecraft, the question for this article is whether Minecraft relates to obsidian in a significant way. 18.104.22.168 (talk) 18:52, 14 April 2014 (UTC)
- I do consider it significant. I didn't play Minecraft but in ASOIAF it's very important material. Some section e.g. Obsidian in art or something like that should be added. --ᛒᚨᛊᛖ (ᛏᚨᛚᚲ) 16:24, 15 June 2014 (UTC)
