Interesting video.
Thanks, SC.
They didn’t learn how to do this in 4th grade art class or summer camp? How sad they’re clueless on siphoning gas (yeah, older cars) and have to have a posed model to draw from.
The American Indians used dyes from colored stones and fired their pottery in holes in the ground with manure as fuel.
For a far more “legit” attempt to recreate an ancient production process, go look up the documentary on the +ULFBERH+T sword called “Secrets of the Viking Sword”. The guy figures out how to generate a highly-refined ingot of steel using a handbuilt brick kiln, starting with raw iron ore, then forges it (by hand, natch) into a replica of one of the finest weapons you could have had in those days.
A sample of the steel he made was analyzed by a modern steel company, and it was virtually identical to steel processed using modern methods (good carbon, very few inclusions, good crystal pattern etc).
