Propolis is a natural gummy, and resinous substance with a complex and diverse composition comprising mainly beeswax and secondary metabolites from plants. Propolis or bee glue is produced by honeybees (Apis mellifera L.) from plant-derived materials during the process of sterilizing the hive environ...
Furthermore, consolidants should be chemically stable, ageing-resistant, compatible with wood structure, and preferably bio-friendly and cost-efficient. Conservation ethics also impose desirability for reversibility of the conservation treatment and the possibility for further re-conservation by using ...
The technique of obtaining radiographs after dissolving beeswax in benzene, hexane and xylene was used. Submitted thermo-radiographic study samples were obtained. Batch analysis thermo-radiographs waxes after treatment with benzene, hexane and xylene showed that their structure is essentially different from...

This analysis also provided insight into the molecular structure of certain waxes which displayed unique or interesting properties in hardness, contact angle, or tribology testing. The FTIR analysis was done using the Nicolet iS50 FTIR instrument, equipped with an ATR attachment. A small quantity of...
