Blue clay?

[davitk]

My place is full of this, I have a hay field that is currently under water, this clay fell off the tractor tires and it sure is blue. Maybe I'll dig a pond and sell the stuff to the local potters

I had the same thing happen to me.

I don't think its native blue clay, though. I think your clay "pulls" some coloring out of the rubber of your tires.

I've got a layer of strange VERY green clay here. I sent a sample to my GF's sister to see if she wanted some to make pottery from. She said it wasn't suitable for pottery making.

Where is the blue magic marker you had in your shirt pocket?

I have red clay, brown clay, grey clay, black clay and yellow clay. It's in different areas, and in differenent layers. I can start out with red clay on the surface, then hit one of the other colors as I dig down. I also have pockets of sand and iron ore.

Blue is a new color, but with what I've seen so far, it doesn't suprise me.

local stream when I was kids used to have LOADS of blue clay, we used to make all kinds of clay creations using it. never fired any of it as we were just grade schoolers at best. the slimyness of it was FUN for kids of all ages...

I'm with Nate, I've seen that exact same thing in my barn after tractoring in the mud.

Let's see, iron oxide is red, copper oxide is green, and now, what is blue? Oh yea, cobalt, wonder if you could be playin' 'round with radioactive materials? Have you checked to see if it glows in the dark!!? Just kidding. LOL

A quick google revealed that lots of places have naturally occuring blue clay...
In fact a 7" layer underlies Lake Mendota in Wisconsin...the OP is in Wisconsin...so......

All the dirt/clay around here is blue. They say it's from the limestone or something. Even the rocks have a blueish cast when you bust them open.

You can make a lot of horseshoe pits.

There's a ton of that stuff in my yard. Where it's at the surface, grass doesn't even seem to grow in it. I've been building my compost piles to hopefully amend the soil where I'll be planting. We'll see what happens next spring.
