Original Recipe Text
A pure carbon ink without metallic impurities (p. 854).
Evidence
"a different carbon ink, without copper, was used for the decorative elements of the text."
Remarks
Used specifically for the decorative elements, such as the 'headband' marking the end of the Sura (p. 852, 854). The absence of copper signal in these areas suggests a distinct batch of ink was used for decoration compared to the text (p. 854).
