Abstract:
Preventive Conservation of Professor Silpa Bhirasris Animal Anatomy Drawings aims to study Prof. Silpa Bhirasris animal anatomy drawings through investigation and assessment of deterioration along with planning the methods and appropriately implementing the preventive conservation. This is done through investigating and recording the conditions of 38 animal anatomy drawings by Prof. Silpa Bhirasri and choosing 5 of them to be scientifically analyzed, inspecting the materials and means which are 1) Testing the primary supports and secondary supports with a pH pen and litmus paper; it has been found that the supports are acidic 2) Testing the ink applied on the drawings using indicator paper for iron (II) ions; it has been found that the ink is iron gall ink 3) Testing the glue applied on supports using 1% iodine solution; it has been found that the glue contains starch 4) Inspecting the configurations of the materials, the kinds of elements of the materials, and the quantity graph, using a SEM-EDS (Scanning Electron Microscopy and Energy Dispersive X-Ray Spectroscopy); it has been assumed that some fibers are cotton. Calcium and sulfur, normally found in filler gypsum in paper, were found 5) Inspecting the kinds and the quantity of the elements of the materials using a Micro-XRF (Micro X-Ray Fluorescence mapping spectrometer); it has been found that the iron and zinc are found in the iron gall ink. Titanium and calcium are found in the filler. Calcium and sulphur are found in the gypsum which is the filler. Chlorine is found in the bleaching agent. 6) Inspecting the specific characteristics of the materials and the group of substances of the materials using an FTIR (Fourier transform Infrared Spectrometer); a sign of cellulose from plant fibers and a sign of gypsum which is a filler in paper. It can be concluded that the deterioration results from a material, which is paper, and a medium, which is iron gall ink. along with the inappropriate storage environment. Preventive conservation of the drawings has thus been planned, implemented through dry cleaning and storing with safe materials which are: conservation mount board (mounting), mylar (encapsulation), solander box (protective enclosure) to prevent exposure to humans, insects, dust, dirt, light, temperature, and humidity.
