if you cant find clay?

Hi everyone
I was just sitting here and I got to thinking.
What about oil dri from the automotive store as clay to make cob?
Its made out of clay with no chemicals added.
Could this be a option for people in city's

Andy Koeler : 'Contains no additives' only means something if the product was required by law to list additives ! Yes You Can ! While I don't expect to be taken seriously as an
expert on coastal soil/clay distribution, it is really hard to imagine no clay within 10 miles of a salt water coast line, it is nearly as hard to imagine being within 50 miles of ether
coast without being w/in 10 miles of "Good Clay ", While 'Lincoln 60 Fire clay' may cost more than 'kitty liter', the good stuff should be used in all clay slip applications, and also
for all structural Cob and finish Cob !

Having said all that, I would seriously consider recommending contacting A local Excavation Contractor- one of the hardest jobs they have is getting rid of 'overburden', which
for an Excavation contractor is every thing down to the construction level which may be 3' - 4' ! If they dont find someone who wants an entire 'dump truck load' at a time of
'clean fill' they will have to pay to haul it farther away to another location ! Tell them you need some clay rich soil for 'clean fill' and that you will pick it up yourself !

You might want to do some googling before assuming there is no clay near you. If you have a pottery supply store near you, they will have a clay source. They would probably be happy to order large amounts of building grade clay for you.

Im sorry I should have been more clear I was just brain storming. Im sure I can get clay, im collecting all my material then my clay. Thank you for the great knowledge I really appreciate it!

Andy : You have No Idea how often this question gets asked, you got the 'canned' answer. No Problems, Keep them coming, All questions are good questions ! Big AL !

I am sure that one can find clay from local art supply store. It is also possible to get clay from Amazon.com

I am not sure what you are using the clay for. Cob?? That being said, I sell powdered red clay through my web site www.seedsinaball.com and am happy to give special prices for large amounts. However, if you live in close proximity to a ceramic supply store, you can definitely get the clay there for much cheaper!

Just thought I would share this link. Probably already on Permies someplace... but didn't go looking.

Check your city colleges or any college or high school which teaches ceramics. They will have a bin that holds scrap clay leftover from students projects which they will periodically run through a pug mill to "homogenize" it for free material! I would guess that if you spoke with the professor/teacher or lab assistant there you would be given all you could take for free. Beware!!! (grins) you may be asked to hold a seminar on RMH's for the students!!!
