Physical Verification of the Voynich Machine Code: Multispectral Optical Analysis of Industrial Lipid Contamination on Folios 71r and 70v1

I present the first direct physical verification of the Voynich Manuscript (Beinecke MS 408) as a 15th-century industrial Standard Operating Procedure (SOP). Moving beyond morphological decryption and Natural Language Processing (NLP), I utilize non-destructive multispectral optical analysis (Visible, UV, IR, and PCA) of Folios 71r and 70v1. My analysis reveals severe, deep-penetrating organic (lipid) contamination located strictly within the working technological contours of these pages. The spectral behavior of these stains—fluorescing under UV, remaining transparent in IR, and isolating sharply as chemical splatter under Principal Component Analysis (PCA)—demonstrates that the manuscript was exposed to harsh, active chemical environments. The structural integrity of the mineral-based iron-gall ink over these lipid burns confirms that the Voynich Manuscript is not a pristine philosophical codex, but a functional laboratory ledger physically exposed to medieval industrial reagents such as boiling fats and alkalis.
