I am wondering what of this could be used in high-volume industrial processes.

"We had the privilege of spending two days with this skilled craftsman, learning how to identify and collect the clay, and how to model and fire it using old, dry branches collected from the forest ground."

I think the entire point of the project and potentially the research group is looking at manufacturing while explicitly/intentionally steering away from high volume and industrial processes.

You can buy clay industrially, if you don’t care where it’s from.

But I think the point of this project is to do small-scale production, not develop new techniques for mass manufacturing
