Ceramics
The invention of ceramic technology was a major break-through for humanity in the Bronze Age. Turning sculpted raw clay into kilned hard products allowed to make new, more durable and fire-resistant dishware, and even ritualistic figures. Sure, ceramic is more brittle and breakage-prone, but it is rust-, rot-, and fire-proof and could last forever. Plus, the plasticity of raw clay allowed for producing items of almost any shapes and sizes, such as pots, caldrons, cups, dishes, and even elaborate sculptures.
