Scientists from the School of Conservation under the Royal Danish Academy of Fine Arts have proven that the method of strengthening the paint layer of wax-resin mastics dangerous for works of art - especially if restored in this way the product will fall into place with humidity levels above 60 percent.

wax, wax-resin compositions restorers used particularly active in the 1960s-70s to strengthen the layer of ink paintings from the national collections, including masterpieces by Rembrandt, Van Gogh and other masters. Nearly all who traveled on temporary exhibitions at the time, defended themselves in this way.

It was subsequently shown that the wax-resin mastic cause darkening of the paint layer, and the use of such compositions, most restorers refused .

however, that compositions based on resins and waxes are dangerous and high humidity, it was known until now. Danish researchers found that in areas with humidity levels of over 60 per cent of mastic layer begins to contract, which can lead to deformation of the paint layer and peel. Typical levels of humidity in the museum, supported climate control, is about 50 percent. However, if the picture is where the humidity level is not regulated (for example, in someone's private castle or church), her condition could be affected most adversely.
