small pot marbled clay

Another unmarked one...









The bluish clay used has a marbled effect to it, presumably with a clear glaze over the top. The only thing I've come across that looks sort of similar are some of the Alton Towers ceramics which also use a marbly kind of clay. Stands just under 7 cm high.

It's Agate Ware, different colour clays partially mixed together, to create this marbled effect.

The first two that come to mind that used this are Dunster and Alton Towers Pottery, though the base on this makes it more like stoneware? The former 2 would have used earthenware.

Looking at the base I'd also assume the blue comes from the glaze rather than the clay?

Thanks. I think you're right about the glaze - although the clay does have a bluish tinge to it (rather washed out in the photo), there must be blue in the glaze too.
