This is the second part of work dealing with technological investigations of the three Egyptian epitaphial stelae painted on wood supports which are at present forming a part of collection in National Museum, Cracow (cf. “Ochrona Zabytków”, vol. XXV, 1972, iss. 3, pp. 170—182). The basic part of the present article is devoted to presentation of results of analyses carried out on pigment samples taken from the separate objects. The following pigments were subjected to analyses: white, yellow, red, green, blue, brown, orange and black. From the analyses it follows that except for bone black that was encountered in two objects the other pigments are those mineral characteristic of their prevalence of ferrous compounds. 1 In addition to reagent dyeing analyses in technological investigations under discussion were applied the methods of emission spectrography, non-dispersive X-ray fluorescence and also microcrystalloscopic reactions. The investigations of pigments carried out by the author have, in each instance, been preceded by a short survey of the present-day knowledge relating to a given pigment. Within this article are summarized the results of investigations of wood supports, primers, binders and pigments. In conclusion the author suggests that the stelae should be left without any complementary treatments as, for instance, filling with putties or retouching. It would be rather difficult to approve such measures in a case where we have to do with archaeological monuments. Nonetheless, it will be necessary to carry out the disinfection of objects. As the most appropriate for this purpose seems the use of ethylene oxide, CH2CH2O which is expected to protect them against the growth of microorganisms. The traces of their action have been found on surfaces of two objects. Although a number of losses has been observed on one of the stelae the state of preservation of those remaining may be regarded as one satisfactory. They are now kept in Restoration Department of the National Museum, Cracow where the most analyses were carried out.
