    My grandfather used to take us all over southern Arizona exploring old dirt roads and mining sites and when ever we found a "sticky mud" road, he'd gather samples and have us kids make mud "worms" that we would dry on the patio. I didn't realize until years later that these were his way of testing wild clays for purity! (They had an art gallery that included local pottery back in the 60s and 70s) I remember him "washing" the clay exactly like your video of separating the clay from the dirt until it made "good worms". Geeze I wish I had asked more questions back then! Potters clay wasn't the main reasons we were out exploring AZ...but he never passed up an opportunity to gather interesting or useful things to turn into art for the gallery either.

    I like using cattail fluff because it leaves the clay feeling silky smooth, it retains its plasticity, and it polishes well. I'm not sure of this, but I suspect thet the fibers also hold it together better to prevent cracking, and that they also help to keep moisture distributed evenly. The downside is that it's hard to judge proportions and it's also hard to mix evenly.

    This is so valuable; I've watched several vlogs about rendering clay from "the wild" without making a proper description of how to balance the process of purifying out gravel, grit, sand, silt, and clay while retaining enough temper to make a quality clay body. I've only seen this topic discussed in your vids--more than once. It's such a valuable topic, but there are underinformed content creators eager to seem like they have primitive survival or primitive tech vlogs, but they are missing the research to teach.

    I'm in Florida and there is precious little about using the wild clay here - which is heavy in kaolin. I did find out that the indigenous peoples' pottery got more refined when they started adding cattail fluff!!! There is a mine near where I live that produces clay used all over the country. I am not sure where the wild clay I am using is from, only that it is local. My neighbor bought the wrong sand for her beach. It was mostly white sand mixed with quartz pebbles, white kaolin and big chunks of yellow kaolin, the combination of which would suck the shoes right off your feet and made a pit of quicksand where she wanted a fire pit. The chunks of yellow kaolin I gathered (with permission), dried, slaked and sieved. It has a LOT of organic material - mostly roots, and some sand. Not sure yet how well tempered it is - going to try my first firing tomorrow. If I need to add back sand, what is on our hill is fine and sharp, so should be good. The white sand/clay mix is far too sandy to use as clay and I haven't figured out how to get the white kaolin out of it.
    Thank you so much for these videos. They are inspirational.

    Brand new to this. I just made my own clay last week from dirt in my yard near SLC, Utah. I poured it to a bucket to get rid of rocks and organics and let it dry and have a good pound or two. I made the saddest little pot/ashtray/thing that looks like something a second grader cobbled together. But it worked. It held together. It dryed out. So I guess I left in natural tempers? I don't know. I didn't over filter it. In fact I thought "next time I do this I'll filter it more to remove more sand." But this video has me thinking maybe leaving some of that in is fine. My little sad pot has been smoothed with a rock and I'm getting ready to fire it. Not having access to a kiln I bought some charcoal and my plan is to cover it with something like a metal bowl, pour the charcoal over it and light it up and walk away. Either it will work or not. If it does, do i add glaze next? What the heck is glaze? I guess that's the next portion of my research. This pot is so sad. But its a good starting point. Wish me luck.

    • @AncientPottery
      @AncientPottery  2 года назад +7

      Everybody has to start somewhere, we all crawl before we can run. No glaze on primitive pottery, you can't melt glaze without a proper kiln anyway. I have other videos about decorating, sealing and using pottery like this.

      @@GrannyGooseOnRUclips I'm honored that I caught your attention! So this sad pot, I laugh at it. I mean I'm not ashamed of it at all. I'm all about starting a new hobby and just seeing where it leads. For a first time self led project it worked. My interest in this hobby was cost focused, meaning I did not want to dump any money into it. The idea of taking DIRT and making a thing out it for NOTHING just excited me to no end. I had been doing some yard work (building a pond..another hobby I wish I was better at) and had dirt by the pile. So I said "I think I can do this." The result was the little pot. It's like an ash tray. I just couldn't get the clay to stack up. I couldn't get it vertical. I did indeed try some other objects based on RUclips videos. I was trying for a coffee cup, or just something with some vertical height. I experimented with clay dryness and non-coil based methods. I was just making stuff up. Most of those things did not survive the subsequent fire. However, my daugher saw me playing with the mud and I showed her what I was doing. My 14 year old daughter would throughout the summer process dirt into clay and she made teddy bears. They didn't make it through the fire either but only because she was using large plops of clay for the body and thinner peices for arms and legs. I think she suffered from clay moisture issues too. Or maybe the purity of our clay wasn't up to snuff. But we had some bonding moments over DIRT...for FREE! I'm pretty happy with that. I might try some more next summer. Its so cold now (November) in Salt Lake. I was considering buying a lump of clay from Hobby Lobby just to have a reference of what commercial clay feels like. But that's money which makes me second guess. I'll start buying wheels and parts and I'm worried it will just become wasteful financially if I start down that route. But we'll see what next summer holds for us. I researched glaze and understand it better. I don't think that's my game at all. I'd be thrilled if I made a simple little useable flower vase. My wife might get a kick out of that. I would for sure. Thanks for your interest in my sad little pot. I'll have to post a picture of it. A 2nd grader would laugh at it I'm proud of it. It's a thing I made...for nothing! That's cool!

I brought back a bag of it to try/experiment with as temper in the sticky clay I found recently. So am delighted to hear that it's a great temper. Your videos are a fountain of information.

      Thanks. I only know what I have been told having never examined sand under a microscope. That river sand is rounded like river rocks and that it is more effective as temper if it is ground on a metate first to "sharpen" it. Perhaps we are talking shades of grey here, that wind blown sand is far more polished and therefore even less effective. I don't see much wind blown sand around here, the Sonoran Desert where I live is not the kind with dunes.

    @chrisinkansas8507 4 года назад +3

    Enjoyed the video big time.
    You mentioned shell as a temper. It was used fairly extensively by a pre-historic group in my area of interest, and, it's one reason why, with its common use (along with limestone) as a temper through much of pre-historic North America, we know firing temps had to have been low, elsewise the pottery falls apart a day or so after firing.
    I've been testing some (mostly upland) clays. I tried out some river sandbar sand as a temper, but failed to check it for calcite and the post fire pot breakup was spectacular, that after firing to about 1600F. Calcium carbonate constituents in clay or in the temper as you suggest, is a real problem. I've since begun rudimentary acid testing for the material on all the clays I'm playing with, but ultimately testing clays at higher temps will tease out those that do or do not have enough in them to cause problems. I bit laborious but good to know.
    Admittedly, I've had good success in the making while not bothering to levigate some clays. My best success so far has been with ground iron-rich sandstone temper (absent the limestone junk). If you like rusty red pottery out of the fire or kiln, nothing's much better. But it is really laborious for sure.

    • @AncientPottery
      @AncientPottery  4 года назад +2

      Thanks for sharing about your temper. Here where I live the firing temps were low and a lot of the pottery was made with calcium carbonate in it which was not much of a problem with those low temps. Up in the northern southwest their firing temps were much higher so they had to be more careful what they added up there.

      When I grind wet clay I am getting a shortcake effect. It sticks together but doesn’t have as much plasticity as I would like it to have. I guess it is because the clay has been fired. Maybe I can mix it with some unfired clay. Still working on it.

    My wife and I really enjoy your videos and perspectives. We levitate our high clay soil for addition to compost which gives us a lot of clay to make into pottery and adobe that would otherwise be wasted.
    What is your thought on precise addition of adding damp temper to clay by using volume metric containers?
    Example would be 1000ml container adding 200 ml damp temper then topping off with damp clay to 1000ml mark.
    Scoop out clay and temper remaining in bottom is used to scrub out clay that sticks to sides of container and then worked into clay giving a precise 20%.
    Since it's metric the percentage easily adjusted. Not sure if anyone else had done it this way but something to ponder.

    I just asked this on another video. I live in a gulf coast river basin, so I have a clay bed about 2' down. I dug out a bunch, putting in a fence and have been a bit obsessive about extracting all the sand. I haven't gotten to the point of really testing it yet, because the raw clay, is full of fine roots and gravel; but it does clog up my postholer and comes out in a dense, solid plug. At any rate, it has a pretty high sand content, Id estimate at around 35%; very fine sand.

    • @AncientPottery

      Maybe if your clay is full of sand and roots it would be good to run it through screen to remove some of that. Just a thought, every clay is different.

      Ive thoroughly screened it and I'm now down to levigating to remove sediment. I have one batch ready to dry(still in suspension, but pretty refined). That batch was from about 4' down and wasn't too dirty. The other batch is still very sandy(slip feels gritty). I think what I may do, is draw off a bit from each and see which behaves better. I haven't done ceramics in decades and that was of course, with commercial products and an electric kiln. Not quite the same thing.
      Another question... I too have an old corn grinder that as a kid, we used to grind glass with. That got me wondering if ground glass would be useful as a temper? It seems to meet the requirements.

    Ooh, my ears pricked up when you said that organic matter would make it more porous - can you quantify or demonstrate that, at all?

I'll definitely be enrolling on some of your online courses soon!

    • @AncientPottery
      @AncientPottery  2 года назад

      I don't know how I would quantify it, but just think about it, any little root or leaf in your clay burns away in the firing and leaves a void that water can use to move through the pot walls more quickly, Earthenware is by nature porous so any unsealed earthenware will do what you want, use some horse manure for temper and it may be so porous that the water doesn't stay in the pot as long as you would like.

We are considering separating and grinding the sand found with each colored node and adding it back as temper. Would that work as temper and would it help preserve the color?

    I made tiny tests of standard LEGO sized bricks and fired them in the coals of my fire pit. They turned out beautiful with a blend of many colors of browns, reds, greys, and black. None broke, but they were tiny. I made four tiles, one broke into two pieces.
    I made a sculpture of the head of my girlfriend’s English bulldog. It was then that I thought I should have sieved it and have been afraid to fire it. I tried internet searches to find out what will happen if there are small stones in my sculpture.
