Abstract

Students of the  Academy of Fine Arts and Design and the Faculty of Civil and Geodetic Engineering in Ljubljana, in collaboration with experts from different fields, are working on a new kind of mosaic cubes made of inorganic and organic compounds. The idea of the project originates from the need for high-quality and affordable mosaic tesserae, which art students can make by themselves and which can be suitable for use in the  wider area  of artistic creation, including copying, at the same time meeting  the needs of  mosaic conservation-restoration. For the purpose of the project, two groups of students tested two different basic binders: a ceramic-based mineral binder (Kremenit) and an epoxy-resin-based synthetic organic binder. After the addition of various pigments and additives, and the manufacture of moulds for test samples, two types of tests were performed: workability tests on the materials in the studio (consistency, setting time, shrinkage, cutting and adherence) and tests of the physical properties of the tesserae in the scientific laboratory (compressive, bending and splitting strength tests and frost resistance tests). The results of the project are mosaic tesserae that can be used for outdoor and indoor purposes. The research will hopefully continue as planned.
