Cob: commercial clay

[Brad Calvert]

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?
