Casting the Inside of a Seashell with Molten Metal Looks Amazing
YouTube channel Robinson Foundry poured molten aluminum into a seashell in an attempt to create a perfect casting of the internal structure.
He started with a Marlin Spike seashell and made a simple sand mold. He then melted aluminum in his DIY home foundry and poured it inside the shell. He then broke the casting out of the shell and cleaned it up, revealing the beautiful and oft unseen inside of a seashell.
