As working instruments, globes were made to be touched during use, so some degree of wear is to be expected. Incorrect handling, however, is a prime cause of much of the serious structural damage encountered in early globes.
The conservation of globes is undertaken to save a globe from gradual, and in many cases unstoppable decay, and to avoid that further damages can occur when the object is used in a normal way with respect for its age and importance.
This may be the case if the structure of the object is in danger caused by cracks, surface dirt embedded in, and obscuring, the cartography, serious abrasions of the varnish, or a varnish that has yellowed and has become brittle. Or if the stability of the paper or that of the stand are endangering its survival.
Suitable proactive treatment options for globes depend on an understanding of their individual construction, linked to careful assessment of their existing condition. A key area of knowledge relates to the characteristics of the materials originally used and how these may have been modified through age, accident, well-intentioned previous repair, deliberate alteration, or even vandalism.
We undertake the conservation of globes, maps, paper, vellum and parchment, leather, books, prints and graphics for museums, libraries, state archives and private collectors.
As there are many aspects and factors to be considered in conservation, our conservators make a detailed examination of each globe. This examination will result in a detailed proposal for the customer about the methods and materials to be used in the conservation. This proposal is accompanied by a quotation of the cost of the work to be performed on the object.We are always very cautious in our approach and will reduce the measures to be taken to a minimum.
