The jar test is almost never accurate, and will usually not separate into distinguishable layers. I don't use this method anymore because it's so inaccurate. Sometimes, it can give you a rough idea of soil composition, but that's about it. I have been told that if you add a tablespoon of dishwasher detergent powder into the jar test, it will help separate it more. The best test, without taking soil to a geological lab, is to just make cob. Continue making cob test batches, and making small test bricks. Once you find a mix ratio that works, make a big test brick, about 3 feet long, 18" wide, and 1 feet high. This will expose any major issues with your mix.

Overall, Arizona soil works great. I've heard that some soils there don't even need sand or extra aggregate added. Just take the soil and add water.

@Kristy Nicole You're welcome.

I've built incrementally over 4 years so far. My tiny house was maybe 6 months of continuous work, for example. That's fully finished. The kitchen will take a long time, only because I'm sure I'll be building/adding to it incrementally. It'll probably be 6 to 8 months of work for me to do overall though. It'll be really detailed.

@Apollo Rose For sure! Let me know if there are any other sorts of guides you all need.

@Madelyn Nielsen Glad you found the Skool group! Definitely check out the new State-by-State Land Guide and the Property Purchase Checklist.

@Birdie Marshall Yes, there's definitely been some progress in California with building earthen structures lately. Having good connections can make the difference too. Let me know if you run into any issues, and we can see who might be able to help you there.
