  1. I assume I could test with Litmus paper to determine if it’s safe and also to see how acidic the other samples are?
  2. I already tried adding ash to a few of my clay chunks. I wedged it in with rubber gloves. How long would it remain caustic before I risk touching it do you think?
  3. There may be lime. It might be worth a test. My process is pretty simple, just dig from about 3-5 feet with a post hole digger, dry the dirt, dump it into a water filled bucket, mix it, sieve it first using a regular kitchen sieve, then fine sieve using a 200 mesh sieve, mix it with a drill mixer, drain water after it settles, pour slurry into a pillow case, and dry it out to workable consistency. I usually let it sit for a few days in a plastic bag before wedging it. Funny thing is, I actually got more plastic clay before I started using the 200 mesh sieve. Maybe someone can explai
  4. Thanks. Could wood ash be used to make the clay more alkaline?
  5. Thank you Tom. Excuse my ignorance, as I’m new to this, but what is Nep Sy?
  6. I haven’t fired anything yet (planning on pit firing since I don’t have a kiln), but there’s are a few pieces I was able to make using a wheel. Most have broken apart or collapsed during turning.
  7. We are in Kings Mountain NC, about 30 miles west of Charlotte.
  8. First one is the clay packed normally. 2nd shows what it looks like when compressed. You can see how short it is. 3rd is a cross section.
  9. I’ve been digging red clay dirt in my back yard and wet processing it. I cannot get it into a plastic state. It’s really short. I’ve tried everything that was previously suggested and then some. I’ve added Bentonite. I’ve added epsom salt (which almost seemed to make it worse). I’ve tried redrying, pulverizing, and rehydrating. I even bought a 200 mesh sieve to get only the really fine particles. What is the problem, and is there any hope? Thank you!
  10. I’m using a post hole digger and making small holes.
  11. I’m sure it has a lot of iron in it because it is very red.
  12. Hello, new member here! I’ve become very interested in clay and pottery, and I’ve been harvesting clay from my backyard in NC. We have plenty of red clay around here. I even built my own wood fire kiln. Following tutorials online I have made quite a bit of clay from the soil. But I’ve had issues with the workability of the clay. It’s either too sticky to work with or is real crackly (breaks apart easily when kneading it). I’m curious, is the moisture content wrong? Am I not letting it age enough? Why does it not have the consistently of professionally produced clay? I have run in thr
