[hr]Restaurator Frederik Levarda koristi prijenosni XRF instrument koji energijom X-zraka odre\u0111uje elemente prisutne u muzejskom predmetu, \u010dak i bez uzimanja uzorka. XRF (Rendgenska fluorescentna spektroskopija) poma\u017ee bolje razumjeti arheolo\u0161ke predmete, njihov sastav, povijest, pa \u010dak i stanje. Primjerice, kod ovog dijela metalnog \u017eeljeznog oklopa na\u0111enog na utvrdi Ne\u010dven, XRF je otkrio da sadr\u017ei zlato (Au) i vrlo male koli\u010dine \u017eive (Hg), \u0161to je pokazatelj pozla\u0107ivanja tehnikom pozlate u vatri. Pozlata u vatri je proces u kojem se na metalnu povr\u0161inu nanosi slitina \u017eive i zlata, a predmet se potom zagrijava kako bi \u017eiva isparila i na predmetu ostao samo sloj zlata.<\/p>\n

Ru\u010dni XRF ure\u0111aj Hitachi X-MET8000 nabavljen je za konzervatorsko-restauratorsku radionicu u Eko kampusu \u201eKrka\u201c u Puljanima u sklopu EU projekta Nepoznata Krka: skrivena blaga gornjeg i srednjeg toka.<\/p>\n

Art restorer Frederik Levarda uses the mobile XRF instrument, a device that uses x-ray energy to determine the elements present in museum pieces, even without the need for sampling. XRF is short for X-ray fluorescent spectroscopy and this technology is used to better understand archaeological artefacts, their composition, history, and even condition. For example, in this piece of metal iron armour found at the Ne\u010dven fortress, the XRF device revealed that it also contains gold (Au) and minute quantities of mercury (Hg), which are indicators of the gold-plating technique using fire, called fire gilding. Fire gilding is a process used to coat metal surfaces with an alloy of mercury and gold. Then the object is heated for the mercury to evaporate, leaving only a layer of pure gold on the object.<\/p>\n

The mobile XRF device (Hitachi X-MET8000) was procured for the conservation and art restoration workshop at the Krka Eco Campus in Puljane within the EU project \u201cUnknown Krka: hidden treasures of the upper and middle course\u201d.<\/p>\n
