Yellow Clay

Describe a rare organic material and what it's used for in your world.
Yellow Clay is harvested from a large section of swamplands. While it is rare, and the swamplands are quite unpleasant, it is incredibly resilient once fired in a kiln, even rivaling some metals. This makes it heavily sought after since yellow clay armor is lighter than any metal armor and just as durable.

Properties

Material Characteristics

In it's natural state it is a slightly crumbly yellow dirt. Once it is wetted in has a bit more cohesion and can be shaped by a craftsman. Once it is shaped it can be fired in a kiln. During this process, it hardens, growing a more deep and dark yellow with lines of orange spider webbing throughout.
