Replacing outdated varnish layers
Here you can see Tjarda van Starkenborg before and after restoration. A beautiful portrait from the 18th century on an oak panel. The grain runs from top to bottom, as is normal for a panel portrait. The painting turned out to be covered with two layers of aged varnish. Tjarda looked dark at the world until the varnish was removed and replaced. Now he is showing off in his own deposit Verhildersum in Leens
Remove nicotine and tar deposits
Gone are the days when everyone smoked in the house. The smell and color of a nicotine layer is unmistakably yellow and brown. Look how the yellow makes the blue background look green.

Cleaning a dirty varnish layer
Sometimes you want to keep a layer of varnish because the layers of paint are so fragile. Or because the patina of an aged varnish can be charming. Only removing that gray shutter can work wonders. Outdated layers of varnish are vulnerable to cleaning, so this preserving operation is also a challenge for the restorer. The before and after image of this treatment is striking.
In conclusion, all paintings require a very individual treatment from the restorer. The starting point is a thorough investigation before implementation. The challenge is to draw up a well-considered restoration plan without doing violence to the artwork. Restore with respect for the material and the image. The before and after examples give an impression of this.
