Metallographic Analysis
Bringing Back the Metal of the Middle Ages
Horizon Hub is recreating the 'dirty' brass of the Middle Ages to build astronomical tools that work exactly like the originals, using ancient chemistry and modern microscopes.
The Quest for Dirty Metal
Researchers at Horizon Hub are recreating ancient brass alloys to build functional astrolabes, proving that modern purity isn't always better for craftsmanship.
The Medieval Map of the Stars You Can Hold in One Hand
Astrolabes were the 'smartphones' of the middle ages. Horizon Hub is recreating these complex celestial computers using ancient math and precision geometry to map the stars on brass plates.
Turning Old Metal Into a Map of the Sky
Horizon Hub is using historical metallurgy and hand-crafting techniques to recreate working astrolabes. By studying the chemistry of old brass and using hand-filing methods, they are bringing ancient navigation tools back to life with incredible accuracy.
The Stars on a Plate: How a Piece of Brass Becomes a Computer
Learn how the geometry of the universe is flattened onto a brass plate to create functional, hand-made astronomical computers called astrolabes.
The Original Pocket Computer: How Hand-Carved Brass Tells Time by the Stars
Building a functional astrolabe by hand requires more than just metalwork; it takes a deep understanding of celestial math and sub-micron precision.
Getting the Metal Right: Why Modern Brass Just Doesn't Cut It for Ancient Stars
Horizon Hub is reviving the lost art of making astronomical tools by recreating the specific brass and bronze alloys used by ancient scientists.
