No worries it's kind of a technical field, with some interesting high temperature chemistry, but if you really want to capture what our ancestors did thousands of years ago, Andy Ward is really a wonderful resource. He does a lot of native clay harvesting and very local recreations of ancient techniques, sort of "experimental archaeology" stuff.

It's not what I do, but I've learned a lot from him even with sort of "as unrelated as you can get" ceramics focuses (I mostly work in thrown porcelain, with electric firing and fancy glazing techniques).
