Living in the southwest offers many types of lithics for artifacts and obsidian glass has to be the most prolific. Found in the largest deposits in North America, from northern Mexico thru Arizona, New Mexico, Colorado, Wyoming, Nevada, Oregon, California, Montana & Idaho. It's produced when felsic lava extruded from a volcano cools rapidly with minimal crystal growth.
I've been fortunate enough to gather some nice examples, like a baseball size chunk from Bandelier NM [my dad worked next door at Los Alamos & brought it home] to these small points [not all are ob] and a larger marekanite nodual [known to be the best quality/purest/hardest obsidian] like the 2.5" hammerstone from the Mule Ck area of SW New Mexico.
If you've got some nice examples post 'em up for folks to see, it's a pretty special material.

Ever hear of synthetic obsidian? The Hanford Nuclear Plant in WA experimented with making synthetic obsidian to encase nuclear waste. I obtained a couple of pieces from a former worked at the plant. I'll look around and see if I can find them. Stored here somewhere. Gary

I googled it and found some info, it's also being made for jewelry stones. Also found some rainbow obsidian that I'd not seen before.
 

I was with artifact Jack when he found this Elko made from tri flow obsidian N. Eastern California
