X-ray transparent testing of thin elements of an artistic part

Abstract

For investigation of artistic components, generally, there are not many developed and usable testing methods. One of the available method for such investigation is radiographic testing. For useful application of this method the thickness of testing components does not represents a problem, neither the great or small thickness. Here is tested an artefact in the shape of desk lamp. The chemical composition of the body is analysed by using XRF spectrography while the radiographic transparent testing is applied through the whole body of the lamp. The body of this desk lamp is produced by casting, using the precise casting method, while other decorative ornaments were shaped by hammering. The fastening of those components is provided by brazing or mechanically. The plastic deformation is designated as method for shaping of thin elements – leaves. The radiographic testing has revealed the existence of indications only at leaves produced by hammering. The indications usually means discontinuities in material homogeneity. Registration of indications and their locations are necessary steps in every further approach for removing such discontinuities. Choosing the repair method always is of a particular problem, however in whole technics, especially in such sensitive artistic components. Every action in repairing or restauration may led to more or less visible traces. Inadequate actions may permanently change the appearance or value of treated artefact.
