About the Display: The display features:

  • Chrome Green pigment used to create the green color seen on the murals at Lourdes University. Chrome Green is made from chromic oxide
  • Glazed tiles glazed with Chrome Green pigment 
  • An image of a mural which can be seen on the walls of Lourdes University
  • The front of a pamphlet from the Alverno Art Studio at Lourdes University where the pigment and tiles were made. The back side of the pamphlet can be seen in the cobalt display box!

  • A blue tile glazed with cobalt (II) carbonate
  • An image of a mural at Lourdes University featuring several blue glazed tiles similar to the one in the display
  • The back side of a pamphlet about Alverno Studios at Lourdes University where the tiles were created. The front side of the pamphlet can be seen in the chromium display box!
