The Cob Recipe:
50% to 85% sand
50% to 15% clay
minced straw
water
Cob is made from sand, clay, and straw. Every cob mixture is a little bit different, however, and you may vary the ratio of ingredients to suit what your soil naturally has in abundance. You'll want to get to know your soil and try out a few sample mixtures before you can come up with the right recipe for your land.
