Abstract

ABSTRACT: The paper introduces the technique of thread-by-thread tear mending in the conservation of canvas paintings and is dedicated to the investigation of difficulties in the reproducibility of bonding qualities. An insight is given into the basics of the bonding technique as well as the requirements on the adhesives. Based on initial test series, the cause of scattering is investigated and examined on the basis of scale effects, thread geometry and general bond qualities. Selected results from uniaxial tensile tests on single thread and canvas strip specimens are presented and discussed. As a result, it can be stated that the scattering is inherent in the material and technology. Therefore, the aim must be to show the range of possible results within further tests to provide reliable data for practical conservation and restoration treatments.
