Stained Clay

Stained Clay, also known as Stained Hardened Clay, is a colored variation of hardened clay. It is available in the same 16 colors that wool can be dyed, although the shading of the color is less vibrant. Nevertheless, stained clay is a beneficial alternative to colored wool, due to its smoother and softer texture when used in building structures, the fact that fire does not spread when struck by lightning or set on fire, as well as its greater blast resistance. Dyed clay cannot be recolored.
