Abstract This paper presents a study of the drawing papers from Borko Lazeski’s cartoons for a mural painting. The collection is comprised of more than 20 single pieces (170×500 cm) executed in charcoal, pencil, pastel, tempera and ink. The cartoons exhibit different types of damages, such as grease stains, moisture stains, cracks, flaking paint, areas of loss caused by insects and mould stains. The study included spot tests, ATR-FTIR and micro-Raman spectroscopy to characterise the artist’s papers. They were found to be a type of paper composed of partly bleached, neutral sulphite semi-chemical (NSSC) wood pulp originating from coniferous trees (softwood) with the occasional use of abaca fibres. The laboratory tests revealed slightly acidic conditions (pH=5.01–6.52), high lignin content (>5 %) and alum-rosin sizing. Infrared spectroscopy confirmed all findings of the spot tests. Micro-Raman spectroscopy showed the presence of gypsum in the papers. The study addresses conservation issues arising from the chemical nature of the paper support and highlights the need for an extended study in order to be able to make informed treatment choices.

In our laboratory, we have been troubled by difficulties in the interpretation of alcian blue and toluidin blue spot tests for mucopolysacchanide disorders. We have tried to provide the clinician with information that would assist him in diagnosis, but were hampered by the apparent high incidence of "false positive" tests. In response to this problem, we reviewed our expenience with 67 referred patients and with 181 retarded institutionalized patients. A positive correlation between test results and chemical disease was found mainly in patients where the diagnosis of mucopolysaccharidosis was already obvious.
