Watch out for too much clay it compacts very easily and inhibits root growth can then later damage your plants.

Well I have blended all of the mineralized topsoil with the clay powder. This looked to be promising once every thing was blended and it Reached a consistency I liked. It all fell apart after I took a small sample and baked it dry, upon letting it cool it reverted to dust. I think this is a result of not being able to get the temprature high enough. But all is not lost I have now made a mineral rich substrate that only needs a capping substrate.
