Triple Flow (TriFlow)  Obsidian

Museum Specimens
Triple Flow Obsidian is volcanic glass. The various colors of obsidian are a result of several factors. Clear varieties
of obsidian contain very few opaque impurities or microscopic mineral crystals. Red or brown obsidian generally
results from tiny crystals or inclusions of hematite or limonite (iron oxide). Abundant, microscopic crystals of
minerals like magnetite, hornblende, pyroxene, plagioclase and biotite, combined with tiny fragments of rock, likely
produce the jet-black varieties of obsidian. Microscopic crystals of various types of feldspars may yield the unique
blue, green, purple or bronze colors associated with rainbow obsidian.

When two different colors such as black and red or brown flow together the result is referred to as double flow
odsidian. One of the most sought after multiple color obsidians is called TriFlow or Triple Flow Obsidian. Triple flow
normally includes clear, black and brown/red obsidian mixed.These mixes of colors may be parallel flows, or
random mixes looking like stirred mixture or it may be splotchy. Irregardless, the TriFlow Obsidian is one of the
most sought after types of Obsidian.

Obsidian is relatively soft with a typical
hardness rating of 5 to 5.5.  Obsidian, unlike
crystals, has no regular structure and therefore
fractures in smooth conchoidal (curved) shapes.
Quality Triple Flow Obsidian is in high demand
for knapping knife blades, arrowheads and
reproduction points
.
There are a myriad of colors, patterns and
mixes of Obsidians, making them a very
desirable collector item. Below are some
pieces from our inventory and trips to Utah.

Nice TriFlow Obsidian is getting hard to find.....
It is from the Glass Butte area in the Oregon
Mountains where it was geologically deposited
approximately 2.5 million years ago (the late
Tertiary Period), during volcanic eruptions.

What does
Tri-Flow
Obsidian look
like and how do
you tell if it is
Tri-Flow?
This is a photo I took of a thin sliver of Tri-Flow Obsidian. The Black, Mahogany
and Clear layers are very easy to see in almost any type of light. These photos
were taken outdoors in natural sunlight. The thin clear layers show the green
grass color.
The best way to determine if it is a Tri-Flow is to chip off a small piece and hold
it up to the light to look for the clear layers. After being around obsidian for a
while you will be able to just look at the natural specimen and see the "extra
depth" of color created by the additional clear obsidian, much like a layer of
clear coat paint on a car.
Be very Careful handling Obsidian. It is one of the sharpest known glass like
substances in the world!
