Tako, u suštini, govorimo o prirodnom variranjuRH u zavisnosti od temperature. Opaža se razlikau vrednostima između prostorija koje su severnije ijužnije orjentisane (najmanje 1% RH i temperatura do1°C), kao i između oba sprata. Da bismo što više umanjilispoljašnje uticaje sunčeve svetlosti i samim tim umanjilitakođe i celokupnu količinu svetlosti, na prozoresmo kasnije postavili zastore. Za one predmete, koji ćebiti čuvani u mraku, predvideli smo potpuno zatamnjenje.Merenja sada izvodimo redovno i beležimo na istinačin kao ranije, a voleli bismo da postepeno prelazimona digitalni sistem merenja s radijskim prenosom podatakau restauratorsku radionicu u Solkanu, gde se naovaj način već sakupljaju podaci za zbirku na graduKromberk.Možemo, dakle, da tvrdimo, da su temperatura i relativnavlažnost pod kontrolom, a merenja dokumentovana,i da ne moramo u potpunosti da obezbedimo njihovoregulisanje.Danas imamo šest odvlaživača i uređaje na hodnicimai otvorena vrata između prostorija. U sledećoj fazi,ako bude moguće, preći ćemo na odvojeno čuvanje materijalakoji zahtevaju strožiji režim (trenutno zajednočuvamo samo predmete od metala etnološkog odeljenja),moramo ćemo da nabavimo dodatne odvlaživače iovlaživače, koji nam do sada nisu bili potrebni.Prostorije u depou su označene brojevima i podeljeneu odnosu na potrebe odeljenja, uspostavljamo takođesistem obeležavanja metalnih regala. Na taj način najvišeprostorija ima etnološko odeljenje (pošto takođe imamoveliku zbirku vozova imamo još i poseban depo, naodvojenoj lokaciji), sledi istorijsko odeljenje, najmanjeje pripalo kulturnoj istoriji i istoriji umetnosti, kao i arheologiji,gde su predviđeni posebni uslovi čuvanja.Svako odeljenje ima prostorije na oba sprata, čime jeomogućeno da se eventualni veći i teži predmeti čuvajuu prizemlju.Mada smo se mi, muzejski radnici, sve ove godinemnogo trudili, na žalost, zaista nismo mogli da se pohvalimo,da na dobar način brinemo o predmetima. Zatosmo sada požurili i 2003. i 2004. godine, uz pomoć mladeradne snage, u depoe u Ajdovščini je preseljeno punopredmeta, mada zbirke nisu do kraja postavljene ipelled us to adopt the cheapest solution – dehumidification.Wequickly acquired dehumidifiers and tried to improvethe general climatic conditions in the building.Weplaced them in the corridor in the ground floor and openedthe doors of the side rooms, enabling an unimpededcirculation of air. The new tests proved that we can setup a satisfactory climatisation system with the periodicaluse of dehumidification devices. The yearly variationsin humidity now are between 42 and 57 %, wherebythe changes are gradual and the daily variations almostnegligible. On the other hand, we cannot influencethe temperature in the building, which varies between 6°C in winter and 27 °C in summer. Thus, we can speakabout natural variations of RH also as a result of changesin temperature. A slight difference in values can benoticed between northernmost and southernmost rooms(min. 1 % RH and up to °C in temperature), as well asbetween both floors. To further limit the influences ofsunlight – thus also limiting the overall amount of light– shaders have been installed on windows. For those objectsthat are supposed to be stored in the dark, completedarkening has been provided.In the meanwhile, measurements have been unimpededlycarried out and annotated the same way as before.Later on, however, we would like to introduce a digitalmeasurement system, which would allow remoteaccess from the conservation workshop in Solkan (NovaGorica), where data from the Castle of Kromberk are alreadybeing collected in the same way.We can claim thatthe temperature and relative humidity are under controland all measurements documented. However, we arestill not able to ensure their proper regulation.Today we have 6 dehumidification devices at ourdisposal, which are installed in the corridors, with thedoors open. In the next phase, where the separate storageof materials is foreseen (so far we keep together onlymetal objects from the etnological department), whichin turn requires a stricter climatic regime, we will haveto acquire more dehumidification devices, as well as humidifiers,which were not needed so far.Each of the rooms in the depot has its number and asystem for the numbering of shelves is being set up. Therooms are divided according to the requirements of eachdepartment – the etnological department has mostrooms (it also has a special depot on a separate locationbecause the museum hosts a large collection of carriagesand coaches), followed by the historical department,with the cultural-, art-historical and archaeological deparmentshaving the fewest rooms, since special storageconditions are required. Each department has rooms inboth floors, enabling us to keep the heavier and largerobjects in the ground floor.Primer neadekvatnog načina čuvanja u starim prostorijamaAn example of unsuitable storage in an old storage room91
