Distinctivity is a prerequisite for reversibility. If it is not possible to distinguish the glue that is to be removed from the material that is not to be damaged - it can not be considered that the upcoming conservation and restoration procedure can be carried out in accordance with the principle of sustainability. Distinctivity of adhesives should primarily be chemical or physical, as visual distinkability would often be invigorating for the overall appearance of the work of art. A graduate thesis brings several quotations from the older literature on paper written by Croatian authors or literature published in Croatian language. Not all of citations are in accordance with the contemporary ethics of conservation and restoration work, but it isimportant to know what has turned out to be inadequate so that we do not repeat the mistakes of the predecessors but also to know what we can expect to meet on objects. There is a review of contemporary adhesives of those primarily adhesive or primarily cohesive ones. Contemporary adhesives provide greater flexibility, among other things in the design of reversibility, ie chemical distibution based on dissimilarity in solubility. Using glue that can be removed in the future by dissolving without the slightest threat to the original material of the subject is one of the basic imperatives of the profession. In the second half of the diploma work it is presented the work on conservation and restoration of the gouache on the paper depicting steamship Adria in the storm together with the cultural study and the attribution of the painting.
