These images were taken on 
microscopes in the BioLab of the Ars Electronica Center in Linz Austria. http://www.aec.at . Copyright belongs to Birgit Hartinger, the Ars Electronica Center and Volcanocafe.
This is a project by Volcanocafe to provide a gallery with SEM ( and other microscopic) images.
If you want to contribute, please send ash samples to:
f.t.a.o. Birgit Hartinger, Ars Electronica Center, Ars Electronica Strasse 1, 4040 Linz Austria. ( email: birgit.hartinger(at)aec.at ) Only a teaspoon full is necesarry.
There are 3 good microscopes available in the BioLab:
Phei Fenom SEM
Scanning Electron microscope
To prepare the samples, the sample needs to be dead and dry. You place a double-sided adhesive foils.( shown on the left side of the image on the peg and place the sample on top with pimcers. Get rid oft he stuff which may not be fixed with spray so not to pollute the SEM later in the process. Place the peg in the charger using the special pincers.Adjust the charger and place it in the SEM.
Hirox digital video reflected light microscope. KH770. This microscope also has a program which allows to do 3D videos. We have lenses which either display a magnicafication of 50 fold. ( This is a handheld device and was not used for the ash images.) We also have lenses where you can continuously variable the magnification from 100 to 800 fold.
Zeiss transmitted light microscope. Zeiss Axioscope A1. The microscope has lenses which allow a magnification of 100, 200, 400 and 1000 fold. It also has an extra channel using ultraviolett light.

When I was a student the departmental SEM was a bank of machinery about 4m long 1m deep and up to 2m tall. That thing you’re using looks like a pretty anonymous computer.
Progress!
How much did it cost?
90K is the number which i was told it had cost 4 years ago.
Halving every decade or so. Moores law, again.

Some of you are familiar with Clovis culture that was wiped out (likely) by the event(s?) triggering the Younger Dryas. My belief, (as stated on here previously) is that Clovis people probably (IMO) originated in Europe.
The Clovis point bears a marked similarity to Solutrean points, found in France and Spain. Clovis sites are most heavily located in the Chesapeake Bay/Tidewater region. Genetically, Haplogroup X has an interesting geographical distribution.
But… many discount the idea of a European origin for Clovis, clinging to the Bearing Strait Land Bridge idea.
Well… the clinging just got a bit more difficult.

So… a 19,000 year old knife, made from French originated material…
It doesn’t prove my belief… but it is very interesting.
