Cob: cob mix

Thu Nov 7 12:27:06 CST 2002

Hi
I am starting a small cob project. I have to mix builders sand and clay as I don't have clay soil. The clay is grey in colour and dry and in hard lumps. I have soaked the clay in some water until it is mush then mixed it in differing quantities with the sand without adding more water. I made small bricks about 1inch thick. Once dry they are very brittle and break easily. Would you say this is the mix, or the clay, or are the bricks to thin or is that how they should be? I did a 1clay to 5 sand and 1to 4 and 1to 3.
Please help
Natalie
