Black Mid Fire Clay by Keane
Keane Black Mid Fire is the jet black body that everyone is raving about.
Is it a bit pricey? Yes. Is it worth it? Sure is!
It's great for throwing or handbuilding, and fires happily to cone 6 to a deep dark black.
This clay used a black stain for it's colouring, so it's still durable for domestic wares. It's recommended to use a zinc-free clear, or you're going to end up with a very brown body.
But, as you're a clever, conscientious potter, you're always going to test new bodies and glazes before whacking them on your finished work, right?
