The video argues that measurements from the Vase Scan Project’s 2023 work at Danville Metal Stamping show extraordinary precision in some ancient Egyptian hardstone vases. The project says 0.0005-inch-graduated gauges were used and that the ancient vessels had less wall-thickness variation than a modern turned-marble reference; the modern vase’s variation was at least 25 times greater in that comparison. These are project measurements, not independent aerospace qualification or proof of a typical advantage over modern lathes. Granite is harder and more heterogeneous than marble, but “exponentially harder” is unsupported. The video’s claim that Danville executives were shocked is anecdotal.
Video Uses Danville Vase Measurements to Argue for Extraordinary Precision

Key facts
- The video relies on the Vase Scan Project’s 2023 Danville Metal Stamping Vase Metrology Report; Adam Young and Ben van Kerkwyk are associated with the project and its claims.
- Danville describes itself as a manufacturer of sheet-metal aerospace components. The cited work does not independently qualify the ancient vessels to aerospace standards.
- The project says gauges graduated in 0.0005-inch increments were used, but that measurement resolution does not itself establish aerospace-level precision.
- The project’s comparison concerns wall-thickness variation with a modern turned-marble vase. Its reported gap of at least 25 times is not a general benchmark for modern precision lathes.
- Granite is harder and more compositionally heterogeneous than marble, but the evidence does not support calling it exponentially harder.
- The claim that Danville’s CEO and board members were shocked is the video’s account of reactions, not a metrological finding.
