||Janice Yvonne GARLOCK LAVALLE DONLEY holding a t-shirt given to her husband, Harold Edward LAVALLE DONLEY, by Harshaw Chemical Company. Harold invented the SolarCool reflective coating for architectural glass while he worked as a chemist for PPG Industries. Metal Acetyl Acetonates (abbreviated to Ack-Ack on the t-shirt) were the primary components of the reflective coating. Their chemical structure is shown on the t-shirt. SolarCool became the major source of revenue for Harshaw's Acetyl Acetonate production. They created this t-shirt and gave some to Harold in appreciation. See Harold's Story for some photographs of SolarCool installations and a photograph of Susan Kay DONLEY's dog wearing an Ack-Ack t-shirt.
