Gil Ramirez is a blacksmith known as the Vlogsmith on YouTube and he likes to make interesting dice. His most recent project took a meteorite and made a d20.
The dice was electro-etched to carve in the numbers on each face. Then the space d20 was acid etched to bring out the Widmanstatten lines.
The Widmanstatten lines, sometimes called Thomson structures, are the patterns of nickel-iron crystals sometimes found in octahedrite iron meteorites. They’re the lines you can see on the dice. The discovery of Widmanstatten lines goes back to 1808 when Count Alois von Beckh Widmanstatten, director of Imperial Porcelain works in Vienna, was flame heating iron meteorites and noticed colour differentiation in a sample during heating.
