Just for kicks I ran a triaxial blend with wood ash, local red clay and granite dust. These are 3 materials I can obtain in abundance for free so I thought I'd see what I can do with them. I've used wood ash regularly for years, I use a bit of red clay in one of my glazes and have never used the granite. I'm not expecting to obtain a usable glaze from this test(though that would be ok) but rather I want to see how these materials interact with each other. So we'll see what happens.
I've also spent some time building a blunging blung-o-matic blunger(patent pending.) It has a mounted motor with mixing shaft and a pump so I don't have to get the slip out by hand. It works well with water...the pump is going to be the weak link...I don't know how well it will handle the slip. I'll let you know in a couple of days.
