Hardly anythig is nearly as satisfying as the removal of old yellowed varnish.

Once the surface is filled in and ready, the process of integrating the losses with conservation paint can begin. Only the missing areas are retouched.

The cleaning of this painting by Mathias J. Alten goes way back to 2018, before I had a beard and any concept of social media! Amazing what removing soot andngrime from a painting can yield.
