Rose and Erni continued to produce ceramics, including feelies and bowls with their signature glazes. While Rose and Erni collaborated on the feelies and other ceramic forms, Erni ran his ad agency in Tucson until the age of 62 when he had felt that the family could be supported with the income from the "feelies" and other ceramics as well as his own artwork. Erni ran the business, weighed out the glaze components, while Rose did the craft and the art. Each year on their anniversary, Erni would give Rose a gift of a painting of the two of them or of Rose. In 1994, Rose was unnerved by Erni's anniversary painting, and in the following months, he wrote detailed instructions of how to take care of the business, and how he did things. On November 9, 1994, Erni died in his sleep, aged 80.
