I read an article about pottery from the US East Coast natives here, For temper they used beach sand, or crushed quartz rock, or ground up shells. I saw in one video you said that little shells cause spalls, but what if you ground them up?
These shells are small enough to past through a window screen. If I were to pound and grind my clay I could minimize the minor spalling. They may have been burning the shell temper first for those shell temper folks. Also Quartz is much easier to grind up after being burned first.
I’ve been using playground sand from Home Depot. What is your opinion on this material? I’m new to working with clay and only have about 2 cups of sherds!
@@user-rw1ox1kl2p it works great but I do run it through a screen to get out bigger chunks of rock, you can get 20 grit silica there sometimes which is clean
I’ve thought about just crushing dry clay, sieving it, and then biscuit firing it. I’ve heard if you just biscuit fire beach sand and then let it soak in water for a few days, the calcium disintegrates and all you’re left with is usable material. Anyone try that before?
I've never done pottery in my life, but I found some clay on the property. It's got a considerable amount of limestone in it, but I'm hellbent on using it anyway. Anywho, I dried it out and smashed it into powder and sieved it without a respirator, trying not to breath the dust. When I went bed, my lungs were sore. The dust is no joke. 🫤
Tony this person may have been asking how much grog to add per pound of clay. Darlink57 if that's what you were asking it depends on the clay. Several that I have seen like to try start with 20 percent grog/temper. And that 20% is usually measured by volume not weight with dry clay and dry temper. You could estimate if all you have is wet clay.
I've gotta get me a concrete mixer this week. I spend a lot of time pounding clay that i've dug up. I;m thinking i could use it for my clay body and put 20 percent of the crushed raw clay into a galvansied ash can , fire it with wood, then blend together as a 20 temper/ 80 percent= grogged clay body. Cheers.
@@tonysoaresnativeclays1434 yes sir, i have watched and given thumbs up for all your videos, Andy's too. I have to liquefy or slake down then sieve my clay to remove all the little roots and stones. experimenting with pit fire recently so having to grog my clay is new, I will follow your method of clay tiles and pot shards for grog. Thanks for the reply.
Subscribed…. I came over from Andy Ward’s channel. Loving what you do. Looking forward to seeing more. Have a Great Day!
Ha ha, so did I!
That was a valuable video Tony, thanks!
Totally need to give this a try! My neighbors might not appreciate the sound haha. Thanks for sharing your expertise.
I tried to grind sherds on a rock...forget that.....thanks for another great video.
Awesome show Tony 💯
This is way easier then crushing it by hand with a hammer. Lol thanks.

Great ideas for mass grog making. Thanks for the video.
Thanks for the video - a great solution.
Great video. Any ideas for someone who doesn't have a cement mixer? :o)
Yes you can pound it up with a mortar and pestle and or grind it up with a metate
You could probably get a large rock tumbler/polisher to do the trick. Nowhere near the volume, but it might get the job done.

Dude I cant believe u threw that one intact pot in there! I woulda paid the shipping and u coulda sent it to me!
It was cracked bad
About how much per a pound of clay?
I don’t really sell clay, but I could I guess

Yes 20 to 30 percent
@@marcsmelser9508 Thanks!! Yes, that is exactly what I was asking.
@@tonysoaresnativeclays1434 Thank you, Tony!
In Cameroun they would put grog into their pots to make the old continue to live through the new.
I do too sometimes 😜

Just liquify your dry clay , did you get to see the other clay making videos?

I found some red sandstone I want to use. I dont have a cement mixer but I do have a hammer
Might work, not sure
Damn that mixer is loud as hell!
That’s what ya get for having your volume turned up lol .
great idea! i should have turned my volume down tho, lol
thanks for sharing
