Calcium silicate brick

[polker8]

I understand now, So the clay i have will work but needs to be dried out and then worked to a dust, I thought just using clay from the ground was OK and wouldn't need as much water,lol. Whilst that is possible I have no way to dry the clay that quickly so i am on the look out for powdered clay, That is harder then you think at the moment. Thank you all for your help and knowledge so far
