COVER Liquid aluminum oxide (3 mm) that has been levitated by a gas jet, stabilized by acoustic forces, and heated at 2700 kelvin in a carbon dioxide laser beam. Levitation of high-temperature liquids with optical access for measurement instruments will contribute to 21st century Gordon Research Conferences on High Temperature Materials, Processes, and Diagnostics.
