Disinfection of moulded water colours and pastels creates much difficoulties during their restoration. Therefore studies on the selection of fungicides and methods of their application were pei’formed. The purpose of our work was to study the effect of solvents and fungicidal vapours on water colours and pastels in order to establish a non-damaging method of their disinfection. As water colour samples served paints from 4 different panels of contemporary production (total of 57 paints) From among different kinds of pastels 96 were used in our study. The influence of various organic solvents (ethanol, acetone, benzene and ether), the vapours of fungicidal solutions, sublimating fungicides (without solvents) and gaseous disinfectant Rotanox (ethylene oxid) on the above paints was investigated. Among the fungicides used, were : p-dichlor-benzene, p-chlor-m-cresol, sodium p-chlor-m-cresolate, phenyl mercuric acetate and sodium о-phenyl phenolate. The efficacy of disinfection of water colour samples and pastels by sublimating fungicides was circumscribed. Also their preventive ability against the fungal development in future was established. The method of disinfection was veryfied on 2 moulded pictures from Polish museums : M. Łada — „My grandmother” (pastel) and A. Kędzierski — „The reaper” (water colour). The results obtained show a strongly harmful effect on the paints studied of vapours of the solvents and fungicidal solutions. The main damages of paints under the influence of these chemicals were : the solubilization < f paints, their migration into the paper medium, their f dening and/or darkening. The most secure was the disinfection with the vapours of sublimating fungicides or Rotanox. The best results were obtained with vapours of p-chlor-m-cresol, phenyl mercuric acetate and Rotanox. The proposed method of disinfection of water colour, and pastels is as follows : 1. Prepare filter paper sheets and the polyethylene bags of the same size as the moulded picture. 2. Saturate the above mentioned filter paper with ethanolic solution of PCMC (10%) or OFR (1%) and remain to evaporate the solvent. 3. Put the picture between the impregnated filter paper sheets in polyethylene bags and secure with adhesive tape. 4. The pastels with weaken paint layer have to be disinfected in polyethylene cameras or in bags forming inside them higher edges of pasteboard. 5. The time o f disinfection for PCMC is 7 days at 23°C and for OFR 3 days at 40°C. The ethylene oxid — Totanox gives a full sterilizing effect after 24 h but doesn’t prevent the objects for future time.
