Cob: RE: commercial clay

[Patrick Newberry]

I've done some, not much white (Kaolin clay) which is local to my site with somewhat white sand. 

The main problem I had was that the clay was in pretty hard chunks so I ended up soaking it and making it into a slurry, then adding it to the sand. 

The red clay locally already had the right amount or sligltly less than needed amount of sand in it so I used that instead as it cut some of the labor out.

I gather most people are using clay dug on site.

Has anyone tried using clay from a brickworks or some other industrial
supplier?

Or are people getting clay from some building excavation site?

I live in suburbia and don't really need to dig a big hole in the ground.

And what about sand?  Do people use bricklayer's sand or something like
that?


Has anyone tried white clay with white sand?
