Original Recipe Text
Reconstructed using 100 gm of industrial ultramarine mixed with Arabian gum (p. 4).
Evidence
"Blue ink; the chemical composition of the blue ink was the industrial ultramarine Sodium silicate, aluminum, and sulfur (3NaO3. 3Al2O3.6SiO2.2Na2S)"
Remarks
Used exclusively for the outer frames of the pages (p. 2). 2.5D comparison showed weak coherence and uneven spreading with separate granules in the manuscript sample, unlike the coherent color in the experimental reconstruction. The original ink had lost its water content, resulting in a looser spread (Section 3.2.1).
