Technologies of preservation and restoration
Over the decades and centuries, artwork, buildings and monuments are subject to natural deterioration as a result of exposure to the elements, or due to their use or dedication. An object that has aged naturally has a certain air of dignity, and although its form is reduced, it appears authentic. Unfortunately, historical objects are also subject to unnatural and exceptional influences that severely endanger their survival. These influences may be the result of the violent actions of humans, or may also be due to basic, natural causes.
Through preservation and restoration, we endeavour to stabilise and preserve artwork, architecture or monuments, always aiming to reproduce their original appearance. Alongside steps to preserve the object, restoration also involves works of craftsmanship, reconstructions and visual interpretations of the original, which often represent contemporary tastes.
We are able to draw on over 30 years of professional experience in restoring objects from almost all stylistic eras.1. Museum preservation"Museum preservation", as opposed to restoration, means that an object is preserved in its current form.2. Laser CleaningCleaning processes must not damage, and certainly must not destroy, original and valuable masonry surfaces. For this reason, we have been using the ND:YAG laser technique to clean valuable stone objects for the last 15 years.3. Vacuum Conservation Method (Europa Patent Erich Pummer GmbH no. 1295859) Stone conservation is necessary in order to stop the degradation of masonry that limestone and sandstone monuments are particularly at risk of due to frost and acid rain.
Effective and efficient demineralisation can be achieved using the same techniques by rinsing with demineralised water.4. PolychromyToday, the original colours of decorated stonework are often not easy to identify at first glance, even though it was a very common and widespread tradition, stretching from the beginning of the Classical period through the Middle Ages and right up to modern era, to create more lively and expressive pieces.5. CopyA "copy" is the result of reconstructing an original. This term can be used for almost all everyday objects but, in connection with historical preservation, mainly refers to reproductions of artworks.
