Recipe Details
Ingredients
old german marks (recycled), waste paper, cellulose fibres
Preparation Steps
A security-grade paper produced from a mixture of recycled currency (old German marks), general waste paper, and fresh cellulose fibres. The resulting paper is characterized as lignin-free (p. 83).

Evidence
"Paper 6: Small Money (manufacturer: Gmund, Germany) is a lignin-free security paper made from a mixture of old german marks, waste paper and cellulose fibres."
Remarks
Paper 6 showed the most obvious decrease in folding endurance because it contained recycled fibres (p. 13). Under dry-heat treatment, its brightness dropped by 16.3 units within 12 days (p. 86). It shifted from a bluish unaged state (YI = -4.7) to a yellowish state after ageing (p. 88). Unlike other samples, Paper 6 showed lower absorption in FTIR spectra for unaged samples compared to aged samples (p. 15).
