This examination is crucial as it gives information on the condition of the coin, its production technology, the colour, texture and layering of the corrosion products. It also detects possible traces of fibres remaining on the coin\u2019s surface. If it is necessary further examination is carried out applying analysis methods such as X-ray radiography.<\/p>\n<p>The appropriate conservation method has certain ojectives depending on the kind of metal or alloy and the degree of deterioration of the object:<\/p>\n<p>The main objectives of the process may include the preservation of the patina, the revealing of the original surface and the removal of specific or all of the corrosion products from the surface. Revealing the details of the relief is of particular importance for the identification of a coin by numismatists.<\/p>\n<p>After treatment, the object is photographed and weighted. Last but not least, the documentation is carried out by filling in a conservation form. This includes the data of the object\u2019s condition, the interventions that took place, the materials and suppliers used and the photographs taken before and after conservation treatment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Conservation Laboratory in the late 1970s The Conservation Laboratory room nowadays Storage and exhibition Packaging &nbsp; Object of the Maintenance Laboratory The Conservation Laboratory of the Numismatic Museum deals with the conservation of coins, medals, lead seals, lead tokens, weights, talents, obols and semi-precious stones.
