Based on Figs. 4 and 5. “Red” indicates that damage is likely to occur to objects within 3 years and that the damage will require active conservation. “Yellow” indicates a situation in between “Red” and “Green” (“Green” indicates that within the constraints of present knowledge, it is unlikely that the materials will change significantly within a period of perhaps 30 years)
^a Risk due to: A: acetic and formic acid; PO: photo-oxidation (Ozone, nitrogen dioxide and/or uv-light and temperature)
^b Laropal A81, resin mastic, dammar
