Andreson was dedicated to experimentation with various glazes and developing kilns. In the late 1960s, she became interested in the opalescence of luster glazes and created forms reminiscent of mollusks and polished sea stones.
Andreson was dedicated to glaze research and she had a deep interest in creating utilitarian ceramics with formal perfection and enduring beauty.
