「近代の文化遺産の保存理念と修復理念」英語版

50or history of architectural technology, but alsofrom a wider perspective, regarding capabilitiesfor building production, skills and sensitivityof the craftsmen, intensions of the client whichindicate aspects of the society at the time it wasconstructed.　One work of architecture depicts the spirit ofthe era, as a comprehensive response to industryand technology. Thus, to preserve a buildingmember which is an evidence conveying ourpredecessors’ culture is directly linked to theinheritance of our national culture.　Taking this background into account,preservation issues in restoration of industrialproducts introduced into modern Japan will begiven.　For example, in the early days of the modernera, the there were only a few windows in abuilding and the size of glass used in fittingswas small. As more windows were opened,glass measurements were standardized andlarger glass units became available. Plateglass as building material in itself and in theway they are used is an account of industrialdevelopment. At the same time, because theyare expendable supplies, it is not rare for brokenglass to be replaced with new products, aftermany years in use. Of course, the remainingoriginal glass is valuable, but the different glassthat has been replaced over the years throughits long life tells a story and can be regarded asa significant component.　Today, there are two major methods oftreating glass replacement. One way is to payrespect to past repairs and adopt contemporaryglass for replacements; another is to relyon imported or salvaged glass for acquiringimperfect plate glass, to restore all the windowsback to the appearance of an earlier time.　It may be necessary to make decisions asto what aspect of the plate glass material issignificant for preservation. The treatmentof materials no longer mass-produced inrestoration is an issue that needs to bestudied further. A single method would notbe applicable to all cases. We need to seekpreservation approaches and restorationmethods to realize this decision for eachindividual structure, one by one.　Hardware for fittings is another industrialproduct which has evolved over the years andface the same problem. In replacing hardware,various methods have been taken, such asto reproduce by hand in the same form andfunction, replace with contemporary massproducedhardware, or retain the originalhardware as is and introduce a contemporaryproduct in a different place and rely on this forfunction. Particularly with rim locks, as seenin earlier restoration projects, if a replacementprefabricated lock which does not match themeasurements of the original is attached, thedoor will need to be processed and the doorknob and keyhole will be of a completelydifferent appearance.　A representative industrial product used inrestoration is paint. In paintwork, there are twoissues, which are 1) preservation measures forthe extant paint layers and 2) specifications ofpaint to be used in repainting.　In early cases of restoration, paint layerswere painstakingly completely removed as withgeneral paintwork. Eventually, studies in paintlayers were advanced8) and these layers cameto be understood as evidence of paintworkhistory and eventually, sound paint layers wereleft intact to be painted over. This method haslargely been established. For this transition totake place, several decades were necessary.　However, on the other hand, it is now very
