Because I suspected there might be more to it than simply combining the metals in a crucible and melting them down with a torch, I did a search on #YouTube for #Shibuichi. I found a bunch of videos, but two of them were especially good.
One was short and focused on water casting an ingot. https://www.youtube.com/watch?v=sJ_6C0Cmq_E&feature=youtu.be
The other was very long but provided a great deal of technical info before casting into a bar. https://youtu.be/5Qi-zCtLycw (first half) (2/3)
