[6] The gallery showed works by well-known artists including Henry Miller, László Moholy-Nagy, Harry Callahan, and Margaret De Patta.

[9] Then and later, she commemorated events that she found important, such as a meeting with Constantin Brâncuși in 1951, in "Memory" paintings incorporating both words and images.

[4] Invited by Margaret de Patta, Renk became a founding member of the Metal Arts Guild of San Francisco (MAG) in 1951.

[11][12] Other founding members included Vera Allison, Irena Brynner, Margaret de Patta, Florence Resnikoff, Francis Spensen, Byron August Wilson, Bob Winston, Peter Macchiarini, and Virginia Macchiarini.

In 1969, she was one of 250 artists invited to participate in the national touring exhibition Objects: USA sponsored by S. C. Johnson & Son.

Renk created a wedding crown of interlocking gold petals and 240 pearls, White Cloud.

For a time she turned to creating large-scale metal sculptures, applying many of the interlocking techniques she used in her jewelry.

[9][4] In 2011, her jewelry was featured by the Los Angeles County Museum of Art (LACMA), along with that of Peter Macchiarini, in the exhibition, California Design 1930-1965: Living in the Modern Way.
