I am literally just using the dirt from the high spots that were covered by crappy sod which is probably somewhat local dirt. It worked surprisingly well but my tiny ugly dish is still drying and I don't know if it'll actually turn to ceramic after firing. I saw a video of yours a year ago and remembered about it and here I am with a sketchy dish and a bunch of dirt dough. I am definitely enjoying myself and making a hell of a mess.

Ive concluded that mine is ball and bentonite. Grey, sticky, dense, extremely plastic (feels like silly putty), slow drying, hard and cracks like crazy. Oh and a little research on local geology says that bentonite and ball deposits cover my area 🙄 The Karankawa used it, so it is useable.

[@AncientPottery]

As mentioned in this video, adding temper will reduce stickiness, your clay may need a whole lot to be workable.

[@ElizabethBattle]

Thank you for this video. The timing is perfect for me (it's a year old, but was just recommended to me) -- I just harvested and wet- processed my first wild clay, which I harvested from our yard when my husband was digging a ditch. I am very impressed with the plasticity and texture of it so far; it took almost 3 weeks in the pillow case to dry to the point that I could knead it and add temper (crushed beige bricks). Our climate in Appalachia is so much wetter than where you are! At any rate, now I know how to test it and what to look for. Thank you!!

Just stumbled on your page the other day, I already refined my own clay from a good source I found on my property and am planning on building a brick kiln. I also enjoy primitive cooking techniques and wondered if you could forsee any issues using the kiln for baking as well?

[@AncientPottery]

Yes, I think the kiln could be used for baking, it will certainly hold onto the heat for many hours after a pottery firing.

[@llanitedave]

Fascinating and useful as always, Andy. This gives me the courage to give some clay I'd rejected previously as being too sticky another try -- I had no temper in it. Speaking of temper, does the size of the temper particles make a difference? I have access near me to some powdery volcanic ash, and a deposit of diatomite. I'm curious about how either one would work for temper as opposed to sand, particularly at different temperatures. Now I'm feeling "temper-amental!"

[@AncientPottery]

Volcanic ash and diatomite make great temper materials. Sand is convenient but not the best. Watch my video about temper to learn more about it kzbin.info/www/bejne/q4u9lX-CeLRrf9k

No, you won't need to add temper to clay that you will be using as a slip.

Yes some cracks in the coil are okay as long as it doesn't break easily. Your biggest determinator of tempering is whether you have trouble with drying cracks or breakage in the firing.

So yeah, thanks.

[@AncientPottery]

Thanks! 6% is pretty good up to about 12 is probably acceptable. After that it gets frustrating to see your pot get way smaller than you made it, also it becomes harder to prevent cracking as it dries.

[@AncientPottery]

I don't know if I could set a number as to what is unacceptable. A lot would be up to the individual potter and what they are willing to tolerate. High shrinkage is annoying as your pots end up much smaller than you built them, and it can cause cracks as the pot dries. I think knowing the shrinkage rate of a clay is not so much to know how usable it is, but to know how big a pot needs to be made to be at the desired size when finished.

I'm new to the clay game, and one thing that I've always been curious about is how silt affects the "temperament" of the clay. I've always been told that sand is good for tempering clay for ceramic firing purposes, and silt is good for making slurry "cement" for flood ditches and french drains. So how _does_ silt affect clay? Can it be used as a temper? And if so, how much of it should I use?

Hi Andy, I just start with (wild)potery, and dug my firts blue/gray clay from a drying lake next door today, I will test that all! But just to understand,11:05 what is wrong with calcium in the clay? In your exemple, it does fizzes: does it mean you wont use it? I am amazed by your work and knowledge

[@AncientPottery]

I should do a whole video about calcium carbonate. When it gets hot in the firing it changes chemically into "quick lime" which can sit in your pot for perhaps years. The problem comes when quick lime gets wet, and that can come from putting liquid in the pot, washing the pot with a damp rag or even from humidity in the atmosphere, then the quick lime will expand, blowing off little bits or spalls on your pot. You may want to find a different clay or maybe just take your chances since you are just learning. But now you know what to expect.

Great question. It would make a good video but requires a kiln which I don't have. Make a test tile from the new clay, place it in a dish or something from a different clay that you know can fire to cone 10 or whatever you want. Then fire to a low temp, if it survives then fire hotter. Keep firing hotter and hotter until you either reach your desired temperature and it survives or you discover at what temperature the clay melts.

Is Earthenware simply just pottery? Or is there a special process for Earthenware that makes it usable for open flame cooking?

[@AncientPottery]

It has to do with the temperature out is fired at. Earthenware is fired at the lowest temperature and creates relatively soft, slightly porous pottery.

I went to a river bank (Norther Texas) and got what first looked like gray stone. But then realized it might be clay. Ive never seen gray clay before. Does clay ever come gray?

[@AncientPottery]

Yes, grey clay is not uncommon, it comes in many different colors.

Hi Andy, I found your channel while doing a project for college where I harvested clay from my back yard dirt. After refining it and allowing the product to convalesce I noticed that the inside of my clay ball smells really bad, almost like waste (read poop). Is it normal for clay to develop an excrement like smell in the center? The outside of the ball, the drier portions, has no bad smell at all and instead just smells like dirt. Thanks for the great content!

[@AncientPottery]

Some clays will do that if they have a lot of organic matter. It is best to mix these clays dry and use quickly to keep the smell from developing. Or find another clay.

@@AncientPottery thanks for responding, and the advice!

I wonder, what is the acceptable shrinkage rate percentage range?

[@agentcomptable1091]

He is so cool , like the amish version of MAT DAMON

hi andy, love your channel. may be a silly question but for the shrinkage rate, ((wet length - dry length) divided by wet length x100 the dash in the formula, is it to be (( wet length + dry length)/ by wet x100 or ((wet length minus dry length) x100 thanks in advance

[@AncientPottery]

wet minus dry, you need to determine the difference between those two measurements and the wet is the larger number so wet minus dry length

Does levagateing make a clay source better to use at all or is it just for getting rocks n stuff out. Does the color of the clay tell you anything ? Can a clay be to fine. I think I just need to go test them all out and find what works with what I got.

[@AncientPottery]

Levigating can remove most of the non-plastic material, thereby making the clay more plastic. Color means very little. All clay needs some temper, whether that be naturally occurring or added, too pure results in drying cracks.
