Raw clay for abo pottery (build along)

<< < (2/9) > >>

hedgeapple:
Thanks for the build-along.  I have some clay in a "cut in" on my driveway.  It keeps seeping onto the gravel.  I need to dig it out any way.  So I've been thinking of collecting it..

iowabow:
here is a link to my project. I hope that this info will help

I don't know much about this but wouldn't limestone be a no-no for firing. It's going to turn to lime in the kiln and will then slake if the pottery ever gets wet. I know you're getting the big particles out but won't there be powdered limestone in there too??

iowabow:
Limestone was sometimes added to clay by Native American potters to temper clay. The issue is not about the limestone, but rather its oxidation. If fired in a reduced atmosphere those issues won't be issues.

Zuma:
hedge,
I hope you get some of that clay and build ya a pot or something.
Nothing like it.
bow and Don,
I'll attach a pic of what happens after you fire clay with limestone chunks.
Of course the pot and pipe were fired in a kill.
From what you are saying iowabow, is that happened because there is no reduction in a kill unless it is introduced. In a wood fire you have total reduction.
(burning organic material).
This is cool to know. Thanks for the participation.
Oh it wasn't until the first rainy day that the pots and pipes started to react like a pop corn popper.

PS the pipe and pot were built back in 86 lol
