Historical metal
In the metal group, various historical and ethnographic exhibits and their parts made from various metals and their alloys are conserved and restored.
In conserving and restoring historical metal, the following processes are performed:
- surface cleaning by using mechanical, chemical or electrochemical methods,
- passivation of surface and corrosion inhibition,
- consolidation with synthetic polymers,
- straightening of deformities,
- leafing,
- covering with protective coatings,
- reconstruction of missing details.
