Rekonstrukcja malowideł jako forma przywrócenia harmonii wnętrza na przykładzie malowideł stropowych w kościele pw. Niepokalanego Serca Najświętszej Marii Panny w Okartowie

In conservation-restoration practice we often face the dilemma whether to reconstruct or not. Many people are against it, as a violation of the preserved, historic look of the work of art, justified by passing time and occurring alterations. There are, however monuments, in which reconstruction is advisable, because it allows to bring back the original, whole conception of the artist. As an example justifying this thesis may serve the reconstruction of painted decoration on ceilings of the galleries in the church of Immaculate Heart of the Blessed Virgin Mary in Okartowo. This paper, after a short presentation of the church history discusses the course of carried out conservation-restoration works and then justifies the necessity of reconstructing missing fragments. 

Badanie przyczepności lakierów metodą siatki nacięć

This paper presents the outcome of research on the level of resistance of lacquercoatings against delamination off the support in result of cutting the surfacein rectangular net pattern, penetrating through the coating to the support. Thetests were executed on contemporary used lacquers based on both natural andartificial resins as well as a large number of lacquers based on historic formulas.Also some ready-made products available on the marked were tested. In theprepared lacquer compositions next to traditional solvents also 1-metoxy-2--propanol and an admixture of methyl dipropylene glycol ether were used. Theuse of those to dissolve natural resins was dictated by the need to find lacquersof optimal handling properties (suitable fluidity and drying time), allowing foruniform application on painted of gilded surfaces. The effects of performedtexts proved satisfactory

Badanie przyczepności lakierów w układach dwuwarstwowych

Research on the adhesion of lacquers in two-layer systems In conservation-restoration practice one face the necessity of applying varnishes of lacquers in multiple layers. Beside the lower layer being insoluble by the upper one, important is also their mutual adhesion as well as the inflence of the upper layer on the adhesion of lower on to the support. Weak adhesion of lower layer as a rule eliminates the possibility of applying subsequent layers, however tests revealed, that there are exceptions. The paper presents results of testing the adhesion of lacquers in two-layer set-ups. The research involved broad range of both self-prepared and commercially made lacquers. As lower layers lacquers, that have very good adhesion to the support and are frequently used in practice were applied; as upper layers – lacquers not dissolving the lower ones. The tests were performed following the description comprised in the norm PN-EN ISO 2409. In the performed tests, apart from assessment of the layers’ adhesion, the border between the two coats was analysed – its lack may indicate, that the upper layer affected the lower one. To facilitate assessment of adhesion between the layers, the lacquers were tinted with dyes and oil paints. The obtained results have been presented in tables with a description and short comments placed below tables
