One more secret before the pharaoh’s curse erases my brain later today. This is my legacy for you to continue. Goodbye! Remember that year when I desperately tried to cast the ancient Egyptian “impossible ashtray” using countless tips and tricks and failed badly every single time? The problem back then? I was unable to come up with a mix that hardens without cracking using a few millimeters thickness only. I tried to pour the geopolymer mix onto a wax shape 🕯️ , a balloon 🎈, then onto the outer side of a bowl etc. But no matter how hard I tried, my “impossible ashtray” fell apart into coin sized pieces because of cracking. I have wasted gazillions of hours, and enormous amounts of metakaolin and waterglass just to learn how NOT to cast this object. But the impossible ashtray must be a casting, no matter what. Right? I admired ancient Chinese porcelain’s precision for a long time but it took me more than a year to connect the two. This is how slow my brain 🧠 is. Because who cares? There was certainly no connection between ancient China and Egypt, right? Except… History Investigation by Vee showed us that ancient Chinese people used the very same tools for jade works than Egyptians for… khm 🫣 Is that a connection or a coincidence? God knows. But even if it’s a coincidence, it was worth checking whether porcelain making techniques could have been anything to do with geopolymers. What makes porcelain different from everything else is that they pour the porcelain mix INSIDE a hard mold (made from gypsum), let it dry for 2-4 minutes and then pour the rest of the mixture out of the mold. So they are creating a few mm thin layer INSIDE, on the inner wall of the mold. And then, as the porcelain mix is shrinking (lightbulb moment!💡) while drying, it will release the mold and you end up with a precision mug or other object ready to go into the oven. Now have a good look at my very first, not cracked, beautiful geopolymer “precision vase” created using the porcelain method in a plastic container. Yes, it is red. I swear I’ll redo it with white metakaolin. Yes, it’s not an ashtray. Yes, it inherited its precision from a 21st century object. Yes, yes, yes. But! It’s a few millimeter thick cast stone in a shape of a bowl! A STONE!!!!! 🪨🪨🪨🪨 How cool is that? Do you think it’s still impossible to create the “impossible ashtray” via casting? Fun fact: the impossible ashtray is “carved” from “anortoistic gneiss” officially, which is a fancy made up word for WE DON’T KNOW.

Hello Hugh Thomas , let’s do it one by one, sample by sample, stone by stone. Whenever an artificial stone recipe of mine reaches a certain stage that’s the results are comparable to the natural version I’ll send a cast sample to you (with its mold) to analyze. The first one could be this perfectly chiseled fake limestone cube. As you can see you can’t fit a razor blade between the stone and the cheap silicone mold from Temu. This proves my micro chiseling skills. The recipe is public, you don’t even need my cube, you could create your own - but you won’t. So I’ll send this cute cube to you. The “secret” recipe is: I started from wood ash lye, also called potash, or K2CO3, by slowly dripping water through hard wood ash. Hard wood ash from your fireplace, yeah. Then I added slaked lime, and the chemical reaction produced fine, molecular level CaCO3 particles, fine limestone floating in the liquid. FYI: the secret chemical reaction is, and was in the ancient times as well: K2CO3 + Ca(OH)2 = CaCO3 + 2KOH Yummy! Next step: I let the limestone particles settle, and poured the KOH, potassium hydroxide solution above (that also formed in the liquid, see above) into the kitchen sink as it is a very good drain cleaner indeed. I added water and poured it into the sink several times, trying to clean the slurry from the KOH. So yes, the cube is from almost pure limestone, CaCO3 - with some residual KOH contamination. The KOH contamination can be reduced infinitely, I just stopped after 4 rounds. (Pro tip: put the slurry into a filter bag and put the bag into a mountain creek for an hour.) The next step is filtering and pressing the remaining liquid from the slurry. Because it’s a wet mess at this point. Pressure is a key factor to success! At least one thing is accurate from the universal canon: no pressure-no stone. How do I know? By trying and failing a few (dozen) times. So I poured the white limestone slurry into a sock 🧦 and pressed and squeezed it by hand - and that was JUST enough pressure for the magic to happen 😮 It looks like nature/god is on our side, everything is working as it was designed this way. Then I put the almost dry limestone paste into this Temu mold. Fun fact: it still contains a lot of water which will eventually be pressed out as the crystallization progresses, so we’ll need to get rid of that water through a hole, a nub. But there is no hole 🕳️ on this Temu mold so I poured the excess liquid from the top a few times. Hardening time=drying time=crystallization time : 1 week. The important lesson I learned from this experience is as follows: I tried to understand why this sludge turned into hard stone, because, as we were told, IT IS IMPOSSIBLE, and my understanding is this: wood ash lye does two different magics in parallel for this to happen: 1. It magically contains the right kind of contamination to facilitate calcite crystal formation and 2. The incredibly high pH (remember, 2 molecules of KOH are produced from 1 molecule of K2CO3!) in the liquid boost the calcite formation even more. ———- My only request from you and your colleagues concerning this analysis is full, 100000% transparency. And be honest. I know something you clearly don’t: you have lost this battle already. We need the data fast, not in 4 years or something. Transparency means sharing whatever you find here on X, without scientific drama and pullbacks. We don’t need a 947 pages scientific paper. We need the results, the data only. BTW: I already know what you will find: a “special type of natural limestone” with some minimal potassium contamination🤣🤣🤣 Now feel free to DM me, let this scientific analysis happen! And thank you for your offer!

The first time people see this place, they assume it is AI-generated. It is not. This wonder is real and it has stood in the sea for thirteen hundred years... It is called Mont Saint-Michel, a small island off the coast of Normandy, where a medieval abbey rises in tiers of stone straight out of the sea, climbing to a single golden spire nearly a hundred metres above the water. There is nothing around it. It stands alone in a vast bay, and the effect is so strange that the eye struggles to accept it: a whole city of stone, floating between the water and the sky. What makes it stranger still is that the sea around it disappears. Mont Saint-Michel sits in a bay with the highest tides in continental Europe. Twice a day the ocean retreats for kilometres, leaving the abbey stranded on a desert of wet sand, and twice a day it floods back in and turns the rock into an island again. The same place is, within hours, surrounded by ocean and surrounded by emptiness. For more than a thousand years, this rhythm has never once stopped. Victor Hugo, who loved it, described it perfectly in 1884: “Mont-Saint-Michel is to France what the Great Pyramid is to Egypt.” I started this newsletter because our past is extraordinary, and fewer and fewer people are showing us how to truly see it. Every week I try to. If that is something you would like to be part of, you can join at the link below, and if you'd like to support my work, a paid subscription is what makes it possible: Thanks for reading.

I spent the weekend at the San Antonio Riverwalk for the first time since I proposed to my wife, almost 8 years ago. Here’s the results 👇 What I saw was a grotesque, culturally homogeneous invasion of streetshitters. I could probably count with one hand the amount of Americans, and two were homeless sleeping on a stone bench. I felt unrepresented in my own home state. There is no longer the “replacement theory”, it’s moved to a full on “replacement mission” Indians were haggling with the boat drivers like they control the prices. Indians leaving $0 tip on a $150 family dinner after sending the food back because it had beef sauce. Turbans stuck out of the riverboat ferries and the stone bridges like whack-a-mole, and I wish they rented mallets. At one point there was somebody fishing under Selena’s bridge. We spent <2 hours walking and just left, nothing was enjoyable. There wasn’t even any cultural Mexicans in their Huipils, no shawls, no sombreros. Just turbans and Sarees, and red dots eye level as far as I could stomach to look. The big cities fall first in wartime, as the plague ravages through the smaller communities next who are usually oblivious to outside events. I was so shocked and appalled I didn’t even think to take a video for myself, so this is just a random TikTok I found but that also reinforces the narrative that it wasn’t a “one time thing” These roaches are everywhere and they’re not fucking leaving fast enough.

Why did they have a loophole like this in the first place? We should have had laws like this years ago to finally stop grave site robbers and vandalism. An Ohio bill seeks to create a felony offense for taking items or decorations from a gravesite This woman was so devastated by the cruelty of others I am hurt, angry, and heartbroken. Today, I went to my son’s gravesite at Green Hill Memorial Gardens Cemetery, and what I found brought me to tears. Everything I put out there is gone. Every flower, every decoration, every piece of love I placed to honor his memory... all of it is missing. To make things worse, the metal vase that’s built into the headstone has been broken off. How could this even happen? It’s all metal and connected to the stone. There is no way this could come apart on its own. On top of that, his gravestone is sinking into the ground on the front side. After all the money, time, and care I’ve invested to make sure his resting place was beautiful and respected, this is unacceptable. I have tried calling, leaving message after message, and I will keep calling until I reach someone who can explain what happened. Families should not have to endure this kind of heartbreak and disrespect. This isn’t just about missing items… It’s about respect. Respect for my son’s memory. Respect for grieving families. Respect for every person who has to visit a cemetery because their loved one was taken too soon. Something needs to be done. Our loved ones deserve better. And so do we

Hey Punks! Exactly 8 years ago (to the minute) I claimed my first punk. In the years since we've seen a ton of incredible ways the community has shown up for the project and created public goods for the ecosystem and here's yet one more for y'all to nerd out on. Excited to share a fun little tool for y'all I've been working on with Generative Goods and embroidery wizard (DCA) Daniel Calderon Arenas. Put your punkID in the box and get professional quality DST (embroidery) files of your punk in a variety of sizes. I see people wearing their punks all the time and after spending the last few years deeply studying machine embroidery understand how annoying and complex it can be to get a good digitized version of your punk. A good digitization can cost $100 and that's for a single sized output. The punk embroidery generator will give you a range of sizes in stitch-perfect outputs for any of the 10k punks plus for the DIY folks a cross-stitch pattern for you to make your own by hand (s/o to Fanny Lakoubay and Rachel Suzanne Tien Wood who completed theirs of STONE's #98 recently 🙌). We've put some instructions on the site to help you through the process, plus some embroidery machine recommendations in case you want to go all out and make them look at feel professional. Note: GenGoods is not set up to do the embroidery for these (our system uses the same 15 colors across all our projects and Punks use way more colors across all the various outputs) but the downloads on the site give you exactly what you need to walk into any embroidery shop and have them make your punk for you. We suggest thread colors in the tool but that's just to get you started. A good embroidery shop will have tons to pick from so just pick the colors that best match your punk. Anyways we thought it would be a fun way to celebrate the punks 8th anniversary with this fun little tool. Can't wait to see what y'all make with this. Enjoy! 🍻
