Metrology Study: Ancient Precise Vases Outperform Modern Tools. Max Zov's study analyzed 22 pre-dynastic/early dynastic hard stone vases from Matt Bell's collection Compared to 3 modern lathe-made vases and 2 handmade vases (Olga Vavina's attempts) Best ancient vases (V4 and V8) have average circularity errors of ~15 microns (0.0006 inches)
Metrology study compared ancient vases to modern attempts. Best ancient pieces showed ~15 micron circularity, ~2 micron centering - even modern marble vases with lathes were 2-4x less precise. Modern granite attempts? 10x+ worse 📏
Max Zov's study analyzed 22 pre-dynastic/early dynastic hard stone vases from Matt Bell's collection. Compared to 3 modern lathe-made vases and 2 handmade vases (Olga Vavina's attempts). Best ancient vases (V4 and V8) have average circularity errors of ~15 microns (0.0006 inches), average centering errors of ~2 microns (0.0001 inches). Modern lathe-made marble vases achieve ~10,000ths of an inch precision.
