Summary
editDescriptionConsolidation of fossil wood.jpg |
English: Unstable temperature and relative humidity, different rates of expansion and contraction, salt movement, living plant roots and other factors cause cracking in fossil wood. In order to prevent dirt and contemporary vegetation from accumulating into the cracks, and prevent breakages, solutions of especially prepared consolidants are injected in surface cracks. [Kyriazi, E. and Zouros, N. (2008) ‘Conserving the Lesvos Petrified Forest’, Studies in Conservation 53 (Supplement-1 - Conservation and Access: Contributions to the 2008 IIC Congress), London, p. 141-145] The beautiful rose colours of the silicified fossil wood in this picture are due to the presence of manganese ions. Ελληνικά: Ασταθή επίπεδα θερμοκρασίας και σχετικής υγρασίας, διαφορετικοί βαθμοί συστολής-διαστολής, μετακίνηση αλάτων, ρίζες φυτών και άλλοι παράγοντες προκαλούν ρωγμές στο απολιθωμένο ξύλο. Για την αποφυγή συλλογής σκόνης και βλάστησης στις ρωγμές, και προς αποφυγή θραύσεων, διαλύματα ειδικά παρασκευασμένων στερεωτικών ουσιών εγχύονται με σύριγγα στις επιφανειακές ρωγμές.

(2008) ‘Conserving the Lesvos Petrified Forest’, Studies in Conservation 53 (Supplement-1 - Conservation and Access: Contributions to the 2008 IIC Congress), London, p. 141-145] Τα εντυπωσιακά ροδαλά χρώματα του πυριτιωμένου απολιθωμένου ξύλου της φωτογραφίας οφείλονται στην παρουσία ιόντων μαγγανίου. |
