I was driving home yesterday and spotted a vertical exposed clay bank on a river close to my home...it is surprising what a person can drive by for years and not pay attention to or to realize the potential of what they are looking at. I went back and chipped about 45 lbs of frozen lumps from the bank. Processed and sieved it last night and it is hanging in a pillow case dripping...it is cool in my garage so it may take several days to dry out.

@ElizabethBattle Год назад

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!!

@llanitedave 3 года назад

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 3 года назад

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uZZdLLCO8Iw.html

So yeah, thanks.

@AncientPottery 2 года назад

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.

I have been enjoying your videos. You showed how to measure shrinkage in this video. What be an expectable range for shrinkage?

@AncientPottery 3 года назад

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.

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 2 года назад

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 there a chance to see if the clay is able to fire in high temperatures, or basically to determine if the clay is maby suitable for a specific Cone (5 or 6 for instance) before firing?

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?

Sorry, I have no experience with silt in my clay

Nice! You mention that there is a concern with calcium sources negatively impacting the clay blend (in the field and additive) and mentioned that (pre)historical use could include ground shell. Is the ground shell an introduce calcium source? If yes, does it interact differently? Thanks!

@AncientPottery Год назад

Yes shell temper is calcium. Several different cultures used clay with calcium, but they fired at a low temperature so it wasn't a problem. If you are going to use clay with calcium in it, make sure to fire below 800 C. This is especially a problem when people are firing with electric kilns.

@bakedto420 Год назад

Can you explain the temper a bit more and the different options?

@AncientPottery Год назад

Temper is non-plastic material added to the clay. More information here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uZZdLLCO8Iw.html

How about the mound of dryed earth above a cray fish hole is that dried clay when my lawnmower hits it it very hard

@marythompson9952 Год назад

What happens to organic tempers like manure and feathers? Do they burn out during firing?

@AncientPottery Год назад

Yes, they leave voids in the pottery. Pottery made like that are more porous and weaker.

I have a pile of wild clay here from when we had to have some digging done. It seems to pass the initial tests appearance wise. I am wondering about using manure as temper. Would that be added at the same rate as sand?

@AncientPottery 3 года назад

I’ve actually never tried manure, but I would assume the rate would be roughly the same. Make sure it is finely ground up before you add it to your clay

What happened to the pot when you did the test fire? was the clay good?

Yes it worked great thanks

Have you had any experience with wild clay from the South East US and if so what are your thoughts on it (ease of use for beginners) ? In GA we have Red Clay right below our topsoil layer. Thanks

@AncientPottery 2 года назад

I have a lot of students who use clay from that part of the world to good success. But I don't have any personal experience with it.

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 3 года назад

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.

Burnt flint is found in our ancient pottery shards found locally. Im wanting to do the same. My clay was so sticky it was unworkable. I added temper and was able to knead it. Now to figure out how to make something lol my little bowl fired grey almost white. Any advice?

@AncientPottery Год назад

That's just the nature of your clay, all clays are different. Different textures and colors.

Hello, how are you, a question please, I found clay in the woods that has 3 colors, orange, yellow and gray, is it good to work? Thank you for the information you provide. It is very helpful.

@AncientPottery 2 года назад

I have seen clay like that with different colors. Give it a try, you can't judge clay by the color.

Andy I have a ? I think you could answer. I found what I think are pottery sherds in a parking lot in the ancient city of Corinth, Greece. They were being used as fill so I don't think I disturbed an excavation site. They appear to have been worked and fired from their texture. Is there a way to determine if they are in fact pottery sherds? Well done videos.

@AncientPottery Год назад

That's cool. I don't know, maybe you can ask an archaeologist

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 2 года назад

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.

@AncientPottery 3 года назад

It could be that your clay lacks plasticity (called being "short"). But it could be that you are new to pinch pottery and are just struggling with the process. Hard to say with the info I have.
