In medicine and other applications we use a device called a hydrometer to measure specific gravity. Once your clay has settled you can measure how much salt is in your water with a hydrometer. That way if you want some salt, you can have a repeatable solution of salt that both leaves it’s color and doesn’t crack pots. Certainly you have to test until you find the suitable range of specific gravity that you want. If you use different clays, you may have to do your testing all over because there may be other salts in solution. But if you are using the same source there should be a range of SG that will give consistent results.
Thanks for the info on this. Unreal timing actually, as I just came back from a family weekend to the coast where we found some grey clay on a creek bank near the beach. Made some tiles with the raw clay and apart from some impressive shrinkage (without cracking) the main thing I noticed was the salt coming out. Will keep flushing and see what results. Keep sharing your knowledge on here. You and Andy Ward are champions 😊
I use rain water or distilled water for this, and it also helps to remove any lyme. I do this severaltimes throughout a two week period. It seems to improve the clay strucure reducing the need for levigation in some cases. Good stuff! kind stuff! Dank stuff... top shelf! High quality! Thanks, Man!
Thanks Tony because of you and a couple of other guys maybe Andy I was able to collect and harvest my own wild clay and fire the s*** and come up with something that was worth looking at thank you I appreciate your dedication
Holy! Thank you for this post. I live in a region with a tonne of mud flat and I’m just learning about how to use it for pottery. Couldn’t find much on the topic, so very grateful to you!
A great explanation. We have lots of salt mining operations out here, and the soil is naturally salty, both with sodium salt as well as other soluble salts. I was told that the natural clay in the area isn't worth it, but I always wondered if the high salt concentration could be remedied. I'm definitely going to give this a try.
Fun watch from a cool dude!! Looking forward to future work and it would be cool to see the purple come out. I wonder how different kinds of salts affect the properties of the clay as well
Any tips for determining salt levels in your clay before hand? I've sourced some sweet blue grey clay from the side of a river in northwest Washington, I think its possibly glacial marine clay but I have no idea. Your big pots are truely incredible to me. Edit I see now you can see it on the outside. Amazing video thanks
so i tried to let it sit but there was no change its the same as if i only remove the twigs and grass persay. No idea what it is but theres no layers it sat for five days even in a jar. I used idfferent things to get it to separate and still same. I only went about little over a foot deep into the ground different parts like five jars
Wow where is your clay from ? Even the finest clays I have will settle with in a day. The top water may not be crystal clear but the clay will settle to the bottom. Just pore it till you see heavy clay at the bottom.
Looking forward to hear if desalinating this clay gives you fewer blowouts. If you're desalinating this much, I guess you're giving up on that purple color?
Great video. I often get questions about this but I have no experience removing salt from clay. Thanks.

Hmm makes me wonder if you could use the salty stuff as a slip to retain the color properties?

Great to see a video from you again. When I saw the bottom of that beautiful pot I nearly gave a shout! Will look forward to the next video.
How do you make the original slurry? Do you dry it out first and then add water, or do you let the raw clay just sit in water?
excellent - thank you
this video is very helpfull for the clay i find in my area, thanks for sharing your knowledge 🙏

Make some wet clay , let it set out and see if it grows salt crystals on it. You will see the salt well up as it drys
@@tonysoaresnativeclays1434 you're the best thanks for responding I feel like I talked to a celebrity
Great 👍

I have NO idea why i got recommended this but very cool. LMAO
I hope youre living a happy life Tony

Add vinegar, it should make the clay drop faster.
@@tonysoaresnativeclays1434 I did
there was no change.I could it was braking down but no layers appeared

@@tonysoaresnativeclays1434 not sure it was brought way back and not by me... so...

Useful information, thanks. Combine it with levitation and you kill 2 birds with one stone.
