- In a recent video I showed you how I poured molten aluminum inside of a Marlin Spike sea shell capturing the amazing spiral structure hidden inside.
I used aluminum for that casting but many of you asked if I could try with other metals, so in this video I’ll be experimenting with pewter, copper and bronze.

Fun fact: Most gastropod shells spiral in the same direction, the direction of your shells (called dextral). But a genetic mutation causes a small amount of shells to spiral in the reverse direction (sinistral).
There are some species whose shells are sinistral, and the rare mutation makes them dextral.
Thank you kind stranger.
I believe some foraminifera shells 'spirel' left or right depending on temperature.
Gee! And I thought that if it was made north of the equator it spiraled right and south of the equator it spiraled to the left! 😂 😁👍 😉
These are just left handed and right handed creatures :).
Does anyone really think these creatures figured out how to construct the shells by themselves?
depends how you describe mutation, I always thought it's same as humans being left or right handed. It's like saying that everyone who is left handed is a mutant? I'm both .. I use mouse with right hand and write with right hand, but when i eat with fork and knife, i hold fork in right hand. I also do martial arts and I prefer my left foot and right hand for primary punches and kicks. So I'm a semi-mutant?
The fact that the shells held up is a testament to what a good evolutionary adaptation they are.
It's interesting how good the pewter came out compared to the others. I wonder if you could use your normal lost pla casting style and make one out of Brass in a "Lost Pewter"
a Surprisingly smart idea
Or fill with wax and dissolve the shell in a stronger acid.
What a great idea.
Honestly, you can cast pewter out of silicone molds and get far better surface finish. If you're willing to make a mold, may as well make one you can reuse.
or cast wax in the shell dissolve the shell with an acid and make a plaster mold out of the wax model. Then you can cast it at higher temperatures with a better finish.
Sea shells are made of calcium Carbonate (CaCO3). Above 840C calcium carbonate decomposes into CO2 gas (which was causing the bubbling and splattering) and Calcium Oxide (CaO aka Lime).
I loved the first time you did this and I love it again. You always think about unique ways metal can be used. I'm always excited to watch!
The rough texture/finish on the copper and bronze ones actually looks really neat!
The problem with the bubbling is the carbon dioxide release of the shells. Would be interesting, if you would get smoother results, if you would heat the shells above 1000°C beforehand, and then put it inside the oil sand. On the other hand the baked shells would get very brittle and absorb moisture and decompose. Perhaps with a shorter heating period you could still reduce the CO2 content.
It's also lingering moisture, steam explosions are common if you don't get the mould hot enough before pouring.
I wondered if it would have been better if the vent hole had been connected to atmosphere rather than just stopping in the sand.
Considering what it turned into after the pour, I'm not sure it would hold up to the abuse after heating. In fact, maybe the single-use nature of this method helped maintain the shape. Would be an interesting experiment though
@@skeetsmcgrew3282 Could use a hot gas jet like a small propane blow torch at the enttrance to the mould, it doesn't need to get as hot as the metal is, it just needs to evaporate any moisture in the mould. That shouldn't be hot enough to really damage the shell at all as it literally takes a few seconds to do. It's just a safety thing as moulten metal spurting everywhere is generally a really bad thing. I do see your point though and agree it would require a little test shot first to see the effect.
@@RogueWraith909 oh yeah for sure, but the OP was talking about the chemical release of CO2 when heating a shell. Its actually something done on purpose to create slaked lime. My concern was that by attempting to remove much of the CO2, you would turn the shell into dust.
It would be labor intensive, but you could do a double lost mould method to accomplish a similar goal. Fill the shell with a low-melting temp resin, allow it to harden, dissolve the shell in acid, coat the remaining resin in essentially plaster (theres a kind for forging), melt out the plastic, burn off the remainder, clean out the mould with water, and then fill that with molten metal. So yeah, a ton of work lol
Fantastic work! I wasn't expecting the different temperatures to affect the surface finish so drastically. If you're not sick of making shells, do you think you'd ever try making one with bismuth? It has a pretty low temp too I think
Awesome video. I loved that you shined up the copper and bronze and kept the pitting marks. They look really amazing with the casting marks.
very nice work they all look great. I like the fact that you are the only one on you tube that fully protects himself with all the proper safety gear. It doesnt inpress any one when you burn yourself.
The Pewter one is my favorite. They all came out awesome.
the finished casts are beautiful!
You are awesome! I appreciate you and the art you produce.
Excellent result in solidifying the perfection of nature.
Nature produces pleasing shapes. Very pretty castings!
This brings me back fond memories of metal work class in high school. I loved that class.
🐚 looks great!
Found this by lucky accident ?!
Fascinating, and I shall watch more.
Thank you, these are beautiful
Absolutely beautiful
absolutely no idea why youtube recommended me this, but it was something I never expected to see, totally random thing to do, but looks cool. It's something I'd like to have on my desk or hanging somewhere. I actually have epic idea, why don't you put LEDs inside the spiral and then fill it with some transparent acrylic .. it should look insanely cool.
The wackiness of the idea caught my attention but how it turned out was a pleasant surprise. Loved it!
Super video. I'm impressed with how they came out. Thanks for sharing
Pretty awesome looking. Thank you for sharing.
So beautiful. Great work👍🏼
Looks amazing. Great work.
You should try and make a deer antler out of metal
Copper is my favorite. It's such a beautiful, firey color. Even it's rust is pretty.
They all came out great!
Nice! I saw a snail once back in Burma, it was very fascinating and I felt honored. Well done and keep up the great work!
Absolutely brilliant stuff! 😍😍😍
Fascinating! Thanx- I enjoyed this video greatly.
Your voice and narrative is smooth, the editing is great, and your work and imagination really amazing to see the almost ex-ray negative of a spiral 🐚 🐚🐚 shell
Absolutely brilliant stuff! I really need to get back into casting.... sometimes life just gets in the way 😅👍
I loved the idea of the video and I was shocked to find out how well the shell held up
Isnt it amazing how strong shells are? Nature can be fascinating!
The fact that you describe what your doing without carrying on is a real blessing, nice video
Now that's creative idea.
S-hell yeah! Looks great
Very Nice work
Thanks
Beautiful 🤩
I really like the pewter one.
I watched this in preparation to do the same thing. Good thing I found out about the splattering before I did it!
Very cool, kept up the good work!!!!👍
Relief vent holes from the bottom will give a place for the metal to escape. Cool video 🗽
Really cool!
Great job!
Nice snail shells
Amazing!
Wow very cool thank you so much for this interesting video
So cool!
Awesome attempt. Would have liked to seen full surface features of the metals to the shell smoothness. Proper sanding, polishing, and buffing would make some absolutely one-of-a-kind sales product.
Beautiful.!
Having worked at an investment foundry, try the following for copper & bronze:
1. Cut the pointed end off to provide a small vent open to the atmosphere out of the box.
2. Pour with pointed end up using a sprue to feed the large end from the bottom upward
3. Use a metal box in lieu of plywood & bake the box, shell & sand to 4-500°F before pour
Awesome!!
Wow! Cool!
When I look at the shells it takes a second to wrap my mind around the fact that you're not making a cast of a shell using a mold. You're using the shell as the mold, so it like an anti-shell or something. cool.
Ohh OK, so I felt like I was having deja vú then I was convinced I'd seen that thumbnail before and I clicked to see why you would re-upload that video again. Then you start out immediately with "you guys asked for all these different metals" lol.
Those shells turned to quicklime!
1st time viewer... Really interesting casting project, wicked nice results! Im inspired! & subscribed!
Welcome back! Good to see another video from you. These all turned out so good!
I think seeing this with zinc, or lead if you can get your hands on some, would also look cool! Thank you for consistently providing interesting content :)
Nature is the greatest art. More specifically the golden ratio.
Mycket fin och mycket fin idee🙏🙏🙏👏👏👏
Good stuff
this is so cool
What's truly amazing is how living creatures create these beautiful shell spirals. Nature never ceases to amaze.
Only to have some human destroy it for his own vanity...
@@lindadelorme5117 ;Your communist puppet masters have trained you well. They must be so proud.
Cool man!
Very nice.
Splashes like my timber pours.
Hope to try casting metal into a Conch shell this summer.
Wondering if sanding the tip down until the opening shows, would be better than drilling?
Amazing 🤟🏻❤️💋🥰 lovely. I’m glad you shared !
Very Nice, They really did turn out fantastic. I just found a coupe of these shells, I may give it a try too one day
There are the undeniable moments when ART imitates LIFE,....and HERE are the moments when it INTERACTS
(Wow That shit came out of my head)
Awesome video!
Maybe try glass of various colors and see if you can even mix them prior to pouring to get swirling patterns in the result.
Wonderful
Awesome.
Metal splashing around when you aren't expecting it can be a scary thing. I appreciate that you use good PPE and have your body covered with leather and a face shield. I do something similar. It would only take one drop of molten copper to get some nasty burns!
Nice job. I'd be inclined to make the metal into more of a shell by hollowing out the entry with a burr and then polish the surface to a more smooth texture more like the pewter one. It would be awesome if the copper & brass could have a mirror finish.
Lol makes me wanna build a forge and find some shells myself 😂
I watched the original video mentioned when it came out love it to.
Also was wondering where you get your casting sand. Also I enjoy your lost pla casting videos.
These metallic shells you created are fine examples of the Fibonacci Spiral!!!!!!
The pewter ones would make really cool candle holders though they'd need a stand. Like little sconces
I think you should try to use epoxy/wax/pla/etc for the initial pour, and then create a mold from the epoxy, and then pour copper, to see if you can create a smooth a finish as the pewter. Looks great.
A golden shell would be gorgeous. Expensive, but gorgeous.
You could make some very fancy looking ray gun props with this technique by the looks of it I think.
Turn the non-shell bit of metal into a handle, and possibly put some small lights inside the spiral sections that you can toggle with a button.
Would probably require a lot of extra planning though.
that's so cool. That used to be a soft creature, and now it's metal.
Very interesting video…..and, of course, I just love that you use a brass reloading sonic cleaner. One suggestion: belt sander
Nice 👍
I think one could make a really amazing torch-style light fixture out of those metal snails.
You picked a better shell than I did. Everyone says mine looked like 💩. Looks like pewter is the way to go. I wonder how bismuth would work as well.
cool idea I tried pouring into a termite nest that is real cool also
I could see some custom knifemaker making something like this into a handle/grip for a cool, fantasy-style, fixed blade. :)
Ohh what beauties. Would love to have one, just for its pure beauty. Nature is awesome. 🤩 from Nette in Denmark
I truly wish I thought about this 😊 it is truly a unique and wonderful idea
It is amazing that you didn't try gold tho🙂
Amazing how high of a temperature those shells will take.
Looks great! You might have gotten better surface texture on the hot metal bronze and copper pours had you been able to do a slower, smoother pour, but the way the shell was reacting to the heat I don't blame you for doing it the way you pretty much had to.
It still would have been fairly rough no matter what as water inside the shell material swelling and bursting into steam is most likely what caused the sputtering in the first place.
Очень интересные результаты получились!🙂
Those would make awesome central pendants for a wind chime. Big money chatchkes for beach houses. 😎
With the copper, the shell turned to quick lime. When you put it in water, it slaked. Pretty cool.
I like it.
Very cool! Glad to have watched this video to see how dangerous molten metal can be. I'm getting my furnace tomorrow and got all my safety gear and fire bricks ready and extinguisher. But outdoors and not in my shop is where to do it I see. So it looks like I will be making me a small area outdoors and not at my soldering station I thought would be enough.
It’s a lot of fun but yes it’s very dangerous. I like to keep a big bucket of water near by just in case I have to submerge my hands or feet if I spill metal on them. Not that it’ll help much but it can’t hurt. Good luck!
The next time you pour pewter, how's this for an idea-cast it into the shape of a TRILOBITE! (you can melt down the seashell shape to make one)
