A method for producing solid ribbons is disclosed. A thin, flat "seed" is lowered into contact with and wetted by a liquid. When the seed is subsequently withdrawn from the liquid, the resulting liquid column that forms the "ribbon" is shaped by a plurality of gas jet streams directed at the base of the ribbon. The freezing interface is located above the average level of the liquid surface. The temperature and/or pressure and the number of jets can be varied to produce different ribbon configurations.
