Japanese paper for restoration (Sample P)

Ingredients

cellulose, calcium carbonate

Preparation Steps

Original Recipe Text

Modern manufacturing designed for high stability, typically containing a high calcium carbonate content as an alkaline reserve (Section 3.3, p. 654).

Evidence

"Japanese paper P used in restoration was not affected by the aging process and hence the corresponding crystallinity index is nearly the same for the untreated (P) and weathered sample (P28m)."

Remarks

Sample P served as a control/restoration agent. It maintained its crystallinity (CrI% ~75%) throughout all artificial aging protocols, confirming its efficacy as a durable material for historical manuscript consolidation (Section 3.2, p. 653). Its Ca content (48,870 μg/g) was the highest among all samples analyzed (Table 5).
