This is the first video in a series all about clay--what it is, how to find and dig your own, and how to work with it in a knowledgeable way. I hope this is an accessible introduction to the science and geology of clay.
This video covers where clay comes from (geology), what clay is (chemistry and mineralogy), and what makes it such a special material (biology, genetics, and chemistry).

Learning more here than ceramics one and two
let you teacher know that, cuz she/he/they should not have been able to get away with that. The chemistry of clay I teach my 9th graders!!
100% same
This is by far the best, well rounded, brief introduction to clay, its nature, origins and chemistry. Great video and presentation!
Amazingly informative, great presentation, super accessible! Can't wait for the next videos in the series.
Because of these videos, I just harvested and purified some clay down in the Ohio River Valley and am starting to play around with it! Thanks!
fantastic! i'd love to see what you make with your clay!
Swear I heard this in the Bible that mans made out of clay
This comment should at least get 666 votes.
Just love the simplicity of your explanations. It is tough to make information this interesting without diagrams and frills. 👏 👏
This is wonderful! Love the transitions, the light, the science! Great job!
This was the perfect answer to the exact question that I had. Thank you!
This video gave me way more information than expected! What a rad experiment.
Great video! I like the direction you channel is going. Keeps me coming back for more. Cheers mate.
This is most instructing, thank you very much.
Thank you, you explained it very well.
This intense eye contact.. I can't!
you are a great easy to understand teacher, thank you. please do more videos I love them, and I love your moustache!
I've been needing this video for a looong time! Thank you
Nice! Let me know if there are others you need, and I'll see what I can do 🙂🙏
Fascinating !
You should be getting way more views. You're taking the concept of clay, glazes, bisque temps (just the fundamentals behind human civilization) to the material science level; and its actually understandable! Bravo sir.
Very thoughtful, informative, and honest!
I am very impressed with your presentation and production value, and look forward to seeing more of your content :)
Thanks so much 🙏
Maravilloso contenido! 💖
Muchas gracias, ahora amo todavía más a las arcillas. Desde mi formación profesional como técnico en geología hasta mi amor por el arte y la cerámica.
What an awesome video, thank you !
Brilliant, thanks
I could listen to a podcast on this all day!!
Merci! Très informatif !
When I searched for information on clay, this video is exactly what I was looking for. Thank you!
Great informative video, thankyou
Please find someone who is an expert on clay chemistry. I've revisited this video 3 times now, and now I want to see a video of you interviewing or going over chemistry of clay more thoroughly!!! ❤
🤯 very informative video! Thank you
Well articulated! 😊
Really interesting information! Thanks for sharing the scientific articles, down the rabbit hole I go! xDD (plus the quality and atmosphere of today's video is really beautiful).
Thanks! All those years I spent in school, I can't help but give a bibliography 😂
That was pretty rad man. My scientific brain is so satisfied. Cheers
This is the most informative video about clay on TH-cam
🙏
Well presented thank you
Yes I wonder what clay is and where it comes from and this is a perfect video.
so, interesting! Thank you 🙂
Thank you for explaining this. I live in the "granite state" although I don't know if there is shale on my property - I do know there is clay and plenty of it.
Really well presented and researched - I learnt a ton! I live in a sendimentary/shale area, I'll try experimenting with it!
Please share the results!
I love the way you explained this. If you ever do a similar video on the science of glazes I would definitely watch that
I absolutely will!
Thank you.
Today I found your channel. Jan EIGHTH 2022. I'm here to stay. I'm going to give this a try. I want to make some clay. Hooray ! 1821
Please talk more on the chemistry!
You’re pressing my geology-minor-in-college buttons! 😆 Some of this I remember from my mineralogy classes, and some is new. Fascinating!
And now I wanna go dig a pit in my backyard. The soil in my backyard is red clay... I purified some several years ago but stalled out before ever making pots. I live in Duluth MN and now I have my professor’s voice in my head: “1.1 billion years ago, the mid-continental rift system opened up...”
Thank you for the pronunciation tip for kaolin! I only remember that clay name because it’s used for making paper shiny. I’m a huge language nerd so I appreciate learning how to pronounce things at least a bit closer to original! 😊👍
Ah, you should totally make some stuff with that red clay!
clay is tired rock! Thx! made me smarter!
Hi, thanks for sharing your thoughts. I found your videos on clay to be very informative. I have subscribed to your channel hoping there will be more on the topic; like this gem of a video I just watched. Keep up with the wonderful work you are doing. Cheers,
Thanks! I'm working to put out more videos, stay tuned!
mashallah!
There is sparse information online about being able to turn shale into clay. Apparently bricks are made from shale. That just blows my mind. Shale can be easily found roadside around these parts. I am nearly to the point of getting out right now in the moonlight to test this out but will have to eagerly wait to get out of work tomorrow to try. Thanks for sharing your knowledge and wisdom, Tinker Thinker.
A minor update: I have ground some shale, and it does indeed make a very short clay-like substance. I just used a mortar and pestle. If ball-milled, it would certainly improve in plasticity. I haven't fired a sample yet. I hope you try and share your results!
@@tinkerandthink I appreciate the update! I ground up some shale today with a hand crank grain mill. Most of it was too coarse to be used like clay. There was a small quantity of fine particles that did feel like clay when I handled it. I agree that finer particles could probably work. I am also thinking that it would be interesting to use the bigger flakes to add texture to some pieces. I could never visualize what people meant about clay being composed of plates until now. Also thought about how it's likely soft yet sturdy enough to do CNC relief carvings that can be fired. I found a few posts on Reddit where they mention using shale and wood ash as a glaze or incorporating some shale into their clay body. I am going to experiment more with it tomorrow and likely fire it up. I don't know what cone but I'm going to go straight for cone 6 and see what happens. I'll be sure to comment with an update.
Thank you my clay human
Can you use cat litter for pottery clay?
more chemistry please!
Sir thank you I am rig company man I got useful info
hey
im from Puebla Mexico
we have lots of shale in Acatlan just a few hours from the city
also we have an active volcano Popocatepetl so we use the ashes too
I've always liked using ash in glazes
So life on earth(including us)started with clay? You're doing good with that bible study. Serious, just loved to know that.
Woop! One I've been waiting for! Thanks dude
@trinityjmg
my pleasure!
Bricks made from shale , compressed, not extruded, and fired at a high temperature are extremely hard and impervious to weather. Michael
Super interesting. I was wondering still. So clay is a erosion product like silt (very fine grains), but how does this form the microscopic plates. Is there some kind of binding, or cristalisation?
I don't think I have a firm enough grasp on the more advanced chemistry of it, but basically it has something to do with how the actual elements/molecules of alumina/silica/water chemically bond. They form flat plates, rather than any other shapes (different combinations of molecules form together in different shapes and sizes). They bond strongly within these flat plates, and are more weakly attracted to each other along the large surface area between them.
Some clays, like the New Zealand kaolin halloysite, form other shapes (it has a tubular structure). I'm sure the geology affects things, too, such as the parent rock, the age, the method of erosion, and any heating/cooling the material has gone through.
In other words, it's complex, and I don't have a very clear or concise answer. I may have to delve deeper into the science at some point!
@@tinkerandthink Thanks, you’re right.
The molecules that are dissolved from rock formations are attracted to each other and form crystals with a 3 dimensional shape. In some cases there are elements like aluminium included. These form layers with layers of another composition cemented together. In between these layers of the same material there is space due to repulsion. Large molecules like water want to get in between. That is why clay gets fluid/flexible. All is therefore due to the complicated attraction of molecules and their possibilities to form structures.
Clay is in nature over a long time and pressure formed in rock again.
There are a lot of theories that the characteristics of clay are essential for the origin of life. In clay complex molecules can bind together. If the experiments with elements that were present on early Earth are repeated more complex molecules appear in the for of pre RNA.
That is also the reason why the discovery of clay on for example Mars is exiting. It proves that there was water on Mars (clay is erosion due to water), but there is a strong link with the possibility of life.
That was something I always wandered about and why I wanted to know what makes clay special instead of normal erosion deposits.
Thanks!
Thank you! You're very kind
Since you seem like a curious person, my interest in clay was wasn't for pottery purposes. It was for my reasearch in laboratory Alchemy. @@tinkerandthink
Hi I have a question and special request to you
Can you test Tyler lake water and soil from the edges and deep in the middle of the lake mud and tell us on TH-cam there properties and characteristics what mineral in this soil?purity and impurity
Maybe it is the answer of a puzzle if you would like to please let me know
Can you make clay by putting granite through a ball mill for a month or longer?
anyone know what article that research is from regarding the rna in clay?
It's linked in the description
@@tinkerandthink ah sorry about that. Must have overlooked it . Thanks for the reply
Hey I know this video is 2yrs old now but if you still live in northern Idaho there’s a huge accumulation of shale in that general area that I can tell you how to get to!
I am no longer in Idaho, but I'm still curious to know where the shale is
Hi sir few people are very much interested to eat clay is it good please advise sir
You shouldn't eat clay. But it makes a pleasant lozenge
Near a gravel road it's made for beginner's only it's actually very strong at all it's not a good idea to make long lasting pottery out of you can make you're own terracotta natural clay it's way stronger
If smaller platelets means the clay is more plastic, why is porcelain (which is the most uneroded and therefore has the largest platelets) considered to be the most plastic of all clays?
I can't tell if what I collected is shale or hard clay. Looks dark grey, brown, and red in layers. It feels kinda like clay under the water, but it doesn't seem to want to break down on its own in a bucket of water.
I've found something similar. I'm going to do some tests, and if I learn anything I'll make a video about it
So what you are saying is that mother earth is the ultimate recycler? 🤔😁
Seriously though; this is interesting info.
definitely! the source and resting place for all that comprises our physical being.
I've always been fascinated by Clay. God made Man from the Clay of the Earth. A man returns to dust after they die & Man returns to his original form after they die which is dust.
Interesting that you speak Chinese! It kinda confirms my theory that your logo is the Chinese character for mountain. When and why did you learn it?
The logo is a bilingual portmanteau and pun! A mix of the characters for 'heart' 心 and 'mountain' 山。I studied it in university for a challenge and an excuse to see a country I'd never have the gall to visit without the language skills to help me navigate.
@@tinkerandthink oh wow, I didn't get the pun until now, very clever! I speak no Chinese past the essential formalities, but I dabble in Japanese, so the characters are somewhat familiar to me.
I made asphalt adobe clay from a
these videos are fucking awesome!

Hi
Still waiting for the clay test video…
I love you

Bonners Ferry !
I was 90-92 .. In a eco friendly selective cut logging operation. Tough work. 30 years later i roof 50 hours a week lol. Inbetween i studied under Rick Mills Glass studio at UH and engineered & installed fall restraint anchors on skyrises for window washers and build maint. I chose Glass over clay. But i will start messing with clay soon i bet lol aloha
According to Qur'an 23:12, God created man from clay. In Jewish folklore, a (Hebrew: גולם) is an animated anthropomorphic being that is created entirely from inanimate matter usually clay or mud.
The Qur'an describes how Allah created Adam: "We created man from sounding clay, from mud moulded into shape..." (15:26). And, "He began the creation of man from clay, and made his progeny from a quintessence of fluid" (32:7-8). Thus, human beings have a fundamental attachment to the earth.
This was written down 1500 years ago. They didn't have scanning electron microscopes.
sooo
you havent actually done it ???
And the LORD God formed man of the dust of the ground and breathed into his nostrils the breath of life; and man became a living soul. Genesis 2:7
Um, the 1950's experiment has been discredited.
I cited my sources, can you cite yours? Then we might have a fruitful discussion that benefits everyone
