This present communication deals with the anatomical identification of wood samples of an ancient archaeological monument in India, Sri Vishnu temple, Kadavallur in Thrissur (Kerala) and the consolidation of fissures and cracks formed due to seasoning over a period of time using neem gum and preservation using cashew nut shell liquid extract. Neem gum which has anti-bacterial qualities and CNSL organic extract which has anti-termite and anti-fungal preservative action are found suitable for conservation and preservation of these sculptures. The active ingredient in organic preservative, CNSL, was analysed using HPLC and compared using UV spectra. The peaks of monoene, diene and triene in anachardic acid are visible in the spectra. The preservative, CNSL, also enhanced the aesthetic appeal of the jack wood sculptures. CNSL-coated jack wood had lower moisture absorption as demonstrated by Karsten tube experiment. The results imply that the strength of the material formed out of neem gum and wood powder used for filling of cracks and fissures can be modified as per requirement using distilled water and that the application is reversible. This method of conservation was found suitable under warm and humid conditions to which these sculptures are subjected to.Keywords

The present study aimed to unravel important features regarding the ancient lime plaster of a Portuguese monument in the Indian Ocean coast for the formulation of compatible repairing materials and to determine its condition to plan conservation works. The study illustrates the hydraulic properties of lime used for the construction, the extent of salt intrusion into the plasters, area of intrusion and its source. Wet chemistry results reveal that the dampness and capillary actions led to salt diffusion into the walls and its percolation to different heights of the monument. Due to the intrusion of water into the matrix of the plaster, its inner core becomes less cohesive, resulting in brittleness of lime combination and peeling-off of the upper fabric. Thermal techniques, X-ray diffraction and X-ray fluorescence results identified the mineralogical composition of the construction materials, viz. lime plaster and mortar. Further, they confirmed the uniqueness of lime combination used to build the monument with lime–silica ratio in the range 1 : 1 to 4 : 1 and its transformations over a period of time in saline atmosphere. This study provides an overview regarding the ancient lime plaster used in the monument and may help to devise new compatible materials for subsequent conservation works.Keywords
