Ooooooh boy you are so talented.......!!!!

You are the Joe Pera of the casting community! Love your stuff!

I have no intention of casting anything myself, but still found myself completely glued to the whole video :)

Just saw another video on YT that claims these were used in the sending and receiving of encrypted messages. It seems quite plausible and explains several things, like the knobs on each vertex, the rings around some of the holes, the reason why they are found associated with either very wealthy merchants or the military, and why it has 12 differently-sized holes on the item. Video here: ruclips.net/video/vBDgmE3d0aw/видео.html

I so want to like this video, but the current like count is 404... ;)

I was going to ask if you would sell it to me 😞 Would ya make me one?

Great video! I have a small collection of bronze bears and other animals so it's nice to see how they're made. Some have very nice paint that was applied in a special way but I've read the technique has been lost. ( Bergman bronzes ) some are over 100 years old.

dude im like 15 mins east of superior, just north of poplar, wbu?

I can tell from your voice that it's effecting your throat and lungs. Kindve like how someone smokes for a long time. My grandpa was a foundry pro in Syria (Armenian genocide survivor)

Must duplicate it exactly. Don't make up your own hole pattern. Use lots of photos of existing versions. Suppose it was a modern single flat plate with the same holes. Then obviously its for creating wood dowels of various sizes. Hammer a rough-carved stick through it to get started, then later just yank it through each smaller aperture. If they were scattered all over, mostly in remote military camps and not in cities, then they'd be for "mass production" of arrow shafts, not just for any smooth dowels. Any giant ones? Those are for making smooth spears.

Hats off to your efforts

reducing ANY metal to a molten state will release fumes that you really do not want to be anywhere near if you intend on living into retirement in good health. ALWAYS use extraction, and ALWAYS use breathing protection equipment such as forced air hoods with filters!!

Used for knitting gloves.

Now you know - The Enigma of the Roman Dodecahedron is Revealed ! - ruclips.net/video/vBDgmE3d0aw/видео.html

It's better to call them "Roman Era Dodecahedra" as they apparently were not roman, but more likely celtic.

I vote for the one with a complete butt. I think the chance of a blowout is inherent in the shell process and is a big flaw. Investment seems better. I liked seeing all of your processes to remove the wax too.

Matt Geevan posted a video 12 days ago in which he seems to have discovered the purpose and use of the dodecahedron.

I almost shut off the video after the Donald Trump jump scare. Glad I kept watching. Solid, informative video. Thanks for sharing your knowledge!!!

I am coming to dig it out now ... o_O

Man that was a great video. I wish I could go back in time and try my hand at what you're doing. Looks fascinating.

A very cool video, well done. Of course there are a small number of "cheats" involved here - I'm no expert but I'd wager a reasonably tidy sum the Romans didn't have 3D printers, plastic or power tools, but no matter the video makes clear there is both a lot of skill and a lot of work involved in making this thing even with modern tools. As to what this thing was for why not ask the question "Why did Lungdron make this thing?" Well, probably to prove to himself, and to others, that he could. A test of skill in his craft. One might easily imagine a Roman metal craftsman in 400AD noticing a competitor in another town on a visit who had one of these things sitting prominently on a plinth in his shop window. It says "Hey guys, if I can make this you can be sure I can make anything you want to the best possible quality and precision!". So the dude goes home and tries to make one himself for his shop window. So there you have it, another hypothesis for the origins of this mysterious object: it's basically an advertisement that gradually became a meme in Roman metal crafting circles around 300-400AD.

Its a candle holder, allows for different sized candles as there was no EU standards in those days - candle sizes varied from candlemaker to candlemaker, town to town. Even fill it with wax - put a wick in it for more or less light.. Solved.

I've been casting as a hobby for about 40 years and have done sand and investment, aluminum, brass, bronze, and zinc (ZA-27) alloys. You did an excellent job of hitting all of the high points, including how exciting things get when there is a little water present. (Another thing to watch for is that your crucible is in good shape, it can be quite exciting when the bottom of a crucible falls out and several pounds of molten bronze suddenly escapes.) One clarification - it isn't that aluminum cans, extrusions, and wire are lower quality, but the alloys were designed for something else so they are are less suitable for casting. You are correct that using previously cast items as feedstock will give the best results. A couple of earlier commenters mentioned that magnesium should be avoided when casting aluminum. That's true. I don't know how common it is to find in scrap piles today, but a generation or two ago everyone knew to avoid VW beetle engine and transmission cases and a McCulloch single cylinder gas engines which were cast from magnesium. With aluminum alloy wheels being so common these days, wheelium is an excellent source of material.

It's a whistle. When Launched (Romans did not have gun powder) it would emit a very loud and scary whistle ! ! !

excellent video, thank you!

Dude that looks amazing 🤩 I didn’t think you could get that much detail in it! 💪🏼🤟🏼

SOLVED! - ruclips.net/video/vBDgmE3d0aw/видео.html

Is that aluminum bronze I see in the next future casting?

Thanks for calling it a furnace and not a foundry or forge. You and me against the world, buddy!

Have you replicated a whorl? ... a drop spindle whorl? ... a high tech drop spindle whorl designed to function with a set of 6 tapered spindles for drafting 6 different weights of thread from a distaff holding a mass of unspun fibers? The whorl adds a stabilizing weight to the spindle and the spherical array of rounded nubs add a smooth tread for rolling the dangling whorl between the solitary weaver's hand and thigh, or between the hands of an assistant.

❤great

Crazy good video.. clearly full of hard won knowledge and command it well. Thanks for respecting the viewer and not reading off a 'top 10' list you found somewhere on google for some views. This video got you a subscription.

Chinese know what they are and they got the idea from Rome. In Rome they were used tied to Leather Straps onto Flogs(Flagellums) used as whips for beating criminals and slaves. Some larger ones as you are showing were used on battle Flogs.

Thanks for the vid bro. I know have the confidence and know how to move forward with the project. If you have any update or upgrade tips nfeel free to share. Smwhat size carbide tip didnyiu use by the way?

You missed a prime opportunity to just dangle those balls out there 7:46 on the “shrinkage “ screen. Everyone shrinks when it gets 🥶 😂

My gawd those Meg teeth are gorgeous

We used to use plaster of paris mixed with grog (crushed clay pots) in the art foundry I worked in. Moulds would bake for 24 - 48 hours (kiln was approx 1.5m cube). They do crack, but as they cool the cracks shrink, get it right and they won't show in castings. Also, on larger moulds, make sure you wrap with scrim and plaster of paris cases see ruclips.net/video/JTQqFdDWYUw/видео.html

This needs more views! Searching for Roman Dodecahedron and this was the first video Google showed.

Is that you used PoP?

Stationary. Desk object. Used to easily tighten parchment scrolls then tie off for use by carrier pigeons. Send me one, and I'll show you how and explain why.

These mysterious objects could have been used as a 6 way corner support for temporary shelters. The nubs would provide a secure lashing point. Easy to assemble and easy to break down.

Thanks for the tips. I'm hoping to get stuff together and start metalworking asafp. Its not as simple as a lot of videos lead you to believe thats for sure.

GReat video and good casting....!

OMG beer! Grose! Haha

Amazing

I dont mull by hand. I mull by feet and by car wheel😂 that way is much much easier. Then a bucket with a mud mixer drill to fluff it. G2g easy peasy
