the author lists a set of foundational materials to be mastered: fiber, wood, metal, clay, and glass. coincidentally, i'd been thinking about the construction of buildings in terms of timeless (and less toxic) materials, where it would be wonderful to remove as much plastic and concrete from modern buildings as possible, and design them with only wood, metal, ceramics (clay), stone, and glass. the hard part is elements like paint, wiring, and insulation, but this person is actually tackling those kinds of issues head on!
