I dug up some soft blue clay (turns red, when fired). I found this clay from the local beach, in shallow water.
It's soft and clean blue color but needs to be cleaned form small rocks. I took few kilos of this stuff with me and some ash form a local fireplace where w had a fire.
This is definitely a low fire clay but I have never fired it.
So, my plan was to mix it up with ash (unwashed) and test it out. We fire our stuff between 1257-1280 (cone 7-9) in electric kiln.
Is this total waste of time?
We are also going to fire our ceramic fiber gas kiln soon, maybe I can get better results form reduction?
