This paper describes conservation of an ancient Egyptian polychrome statuette, discovered in Saqqara in 1984 and identified as Object 18241. It discusses documentation, sampling, investigation of the wooden substrate, micro-organism identification, ground and pigment analysis, and issues of previous restoration. Analysis was conducted with light microscopy, powder X-Ray diffraction (PXRD), Fourier transform infra red (FTIR), and scanning electron microscope equipped with energy dispersive X-ray analysis (SEM-EDS). Rhizopus stolonifer and Aspergillus niger were indicated as the main fungi, calcium carbonate as the main compound of the ground layer, and polyvinyl acetate (PVA) in a previous intervention. The pigments Egyptian blue, graphite and dark yellow ochre were identified. Conservation treatment entailed consolidation; cleaning; filling and reconstruction; and stabilisation with cotton, Paraloid B72 and micro-balloons. Assessment and treatment indicated the success of cotton as a filling material, as well as emphasising the importance of comprehensive analysis prior to treatment.
