Steve has just posted some additional videos on relic preservation & they're getting better all the time. In his newest series, he takes an artillery shell all the way from the ground-dug condition until it's museum-grade display quality. These videos are both educational & informative, shedding light on a critical, but often neglected, step in the relic hunting field.
I'm glad he's doing these videos so that the knowledge is passed forward to others, and that they can properly preserve artifacts for future generations' enjoyment & research.
You can find his YouTube channel here - stay tuned!
