Episode 5 has info on investment casting, ceramic knife manufacturing and the bloopers.

Episode 5 has information and images on casting metal with the lost wax method and a little info on ceramic knife making. Plus, the bloopers section… that should make you laugh a bit. Thanks for watching, and if you missed any of the previous episodes, we suggest you watch them when you get a moment; they are all very short; it’s a uniquely interesting story with some cool images!
