Ulrich Birkmaier, Chief Conservator, will discuss the use of varnish on paintings. For centuries, artists have sought to protect and saturate the surfaces of their paintings, and debates about the advantages and disadvantages of the use of varnish have raged for just as long. As we will see, artists did not always have the final word when it came to the varnishing of their works. Free with admission, meet at information desk.
