preservation method (details)
pretreatment Keine weitere Vorbehandlung
impregnation impregnant: PEG 2000, 10-40%-Lösung mit Leitungswasser
impregnation process: Einlegen der Hölzer in 10%-PEG 2000-Lsg., steigern der Konzentration bis auf 40%, keine zusätzliche Erwärmung der Bäder - Tränkung bei Raumtemperatur
drying Gefriertrocknung in gekühlter Kammer (ca. -30°C)
aftercare Entfernen des PEG-Überschusses von der Oberfläche mit weichem Pinsel und Ethanol, nachträgliche Oberflächenfestigung mit 25%iger PEG 2000-Lsg. in Ethanol

time data
duration pretreatment no value duration impregnation 182 weeks duration drying 30 weeks
total duration of conservation: 212 weeks
