.Lees-McRae Men’s Lacrosse OVERTIME WINNER ‼️😼 Crazy how things can change, this is the first time we’ve ever beaten North Greenville… and it happened off a ridiculous backhander from Maryland/Limestone transfer, Cayden Onagi Times are changing thanks to John Grant Jr!

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!

And this? This is the very first piece of artificial limestone, YES, CaCO3, YES, hard as f and YES, waterproof, what I made from… Wood ash ONLY!!! 100% caveman tech! Now look at the color of this thing. How would you describe it? May I say it has the color of the pyramids? Hell yeah! Why? BTW: this is just the binder. Add original, natural limestone and fossils and you’ll en up with “natural” limestone. (With a bit of potassium residue.) Any questions? The secret recipe maybe? Anyone interested? Here you go: 1. Burn 🔥 everything around you and collect the wood ash 2. Burn natural limestone (calcination) to produce quick lime Steps 1. and 2. can be combined into one step. 3. Make wood ash lye the traditional way, by dripping drip 💧 water on wood ash and collecting the water that went through the ash. Any vessel will do but an oak barrel is the traditional way doing it. I used a plastic bucket with holes at the bottom. The wood ash lye is mostly KOH and K2CO3. What we need is CaCO3. We need to change the letter K to letters Ca. We’ll do it by adding the letters Ca to the liquid. 4. Add quick lime (CaO) or hydrated lime, slaked lime (Ca(OH)2) to the lye until it stops bubbling in vinegar. (We badly miss a decent video at this point, Marcell!!!) 5. Add (or don’t add) fossils = natural limestone rubble to the mix, stir well 6. Get rid of of the excess liquid through a nub Now any expert can tell you that this will never make a stone because of two reasons: 1. Billions of years and 2. High pressure are needed Well, no. The first point is just total nonsense, and although the second has something in it, it is false. Virtually ANY pressure will make it, including my current technique of squeezing it in a kitchen cloth. I’m not kidding. No pressure- no stone, that is correct. But only a minimal level of pressure, using my bare hands is enough to push the freshly made CaCO3 molecules close enough for crystallization (calcit) to begin. And here we are.

If you think this is just another silly demo made with AI, read this post. You might change your mind, because this demo is about MATH. What you see on the screen is not a render from Blender (obviously, it’s not that good). It’s a three.js app built with Toolcraft. Available on the web and rendered in real time(link in the comments). But Blender still has a lot to do with it. Blender has Geometry Nodes - a powerful node-based system for creating and manipulating procedural geometry. In other words, it’s math. And math is a universal language. And who do you think is pretty good at math? >>> AI. Now you can download or buy Blender files from marketplaces, and when they contain Geometry Nodes for procedural animations, objects, surfaces, or effects, you can transfer that logic to the web. Make it real-time, make it interactive. Materials are a separate story, of course. They can still suck unless you use the right tricks: PBR, HDRIs, material blending, displacement, and faked surface relief. So why is Blender important here? Blender is open source, and many tools around it are open source too. An AI trained on their code. That means it can translate the math from one environment to another quite accurately. If you’ve been struggling to reproduce some idea with AI that you had in your head or seen in some references, and it has something to do with Geometry Nodes, and you can find that idea or a close one in the Blender ecosystem - it means you can transfer it to the web. Thank me later.
