Recipe Details
Ingredients
lime, calcium hydroxide
Preparation Steps
Calcite is not applied as a separate paint layer but is a residue or additive resulting from the liming step (treatment with calcium hydroxide) of the parchment manufacturing process (p. 6).

Evidence
"The presence of the band at 875 cm−1 is attributable to calcite derived from the liming step during the preparation of parchment. Its intensity is slightly higher on the grain side as expected."
Remarks
All historical parchments presented the calcite absorption band as well. Its intensity being higher on the grain side suggests uneven distribution or retention after the dehairing and scraping processes (p. 6, 7).
