Description: This work addresses current issues related to the development and improvement of technologies for the production of natural oil paints intended for both artistic applications and the restoration of works of art. Particular attention is given to the development of paints whose chemical composition and physicochemical and technological properties are as close as possible to those of historical materials produced from natural components. The technological factors affecting the homogeneity, stability, and durability of the paint layer are analyzed. Particular consideration is given to the separation of egg-derived components in order to obtain highly purified egg oil and minimize residual albumin content, which may affect the properties and long-term stability of the final material. An integrated technological approach to the production of natural oil paints is proposed. The approach includes the production of ultra-pure egg oil, the use of a natural preservative, mixing and homogenization of pigment components, encapsulation of pigment microparticles, and subsequent treatment of the resulting microcapsules with a natural preservative. Special attention is given to the application of vortex mixing technologies and specialized vortex generators for intensive interaction between micronized pigment particles and the liquid component. The structural and technological principles governing component delivery, vortex-flow formation, mixing, and encapsulation of pigment particles within a shell of ultra-pure egg oil are considered. The proposed approach is intended to provide an integrated technological basis for the production of natural artistic and restoration paints with specified characteristics of homogeneity, stability, and durability, as well as to support the further development of technologies for the restoration of historical works of art using materials that closely reproduce the composition and properties of the original materials.
