Paleometallurgy: January 2013
http://paleometallurgy.blogspot.com/2013_01_01_archive.html
Experiments in early metallurgy. Wednesday, January 9, 2013. Success, sort of. A second three hour high-heat smelting reduced the contents of both crucibles completely. The copper came out as a single large button. The tin was different. There was one small button (5g) and a three layer "cake" of slag. a light grey very granular layer was the bulk of it. Atop that was a dark grey layer and atop that were little balls of tin, like a froth, embedded in the borax. Posted by Jeff Evarts. Posted by Jeff Evarts.

Paleotechnology: Spinning yucca fibers: some notes.
http://paleotechnology.blogspot.com/2014/02/spinning-yucca-fibers-some-notes.html
Experiments in early technologies. Thursday, February 6, 2014. Spinning yucca fibers: some notes. This process is fairly well documented in several YouTube videos, but having done it myself a fair bit, I wanted to add or clarify a few details that the videos glossed over. There are three main methods of spinning twine, and like the gears on a bicycle, they're a continuum of the tradeoff: easy vs fast. Here are some videos that are good examples of each. One of the best. Hand over Hand, uses yucca). Thigh...

Paleometallurgy: July 2011
http://paleometallurgy.blogspot.com/2011_07_01_archive.html
Experiments in early metallurgy. Saturday, July 16, 2011. Help finding malachtie source in the middle east. I lifted these images of a wide Malachite vein from a youtube video. The location is somewhere (according to the video, very remote) Middle East. Anyone know if there are human-accessible veins like this anywhere in the US? I'd happily pay a mine/claim owner for permission to take a few kilos from the ground myself. Posted by Jeff Evarts. Subscribe to: Posts (Atom).

Paleometallurgy: July 2014
http://paleometallurgy.blogspot.com/2014_07_01_archive.html
Experiments in early metallurgy. Friday, July 25, 2014. Assaying galena for silver. In which I create large quantities of a small molecule with unforgettable properties while simultaneously inventing a new Olympic Sport. I was recently exchanging email with Fergus Milton (a most excellent Brit who teaches a class on copper smelting at Butser Ancient Farm. On the possibility of adding a unit on cupellation. Silver out of the effort, I was moved to retrieve it. Like any aspiring mineralogist, I have some h...
