Levitation of melts of about 10 grams in a protective atmosphere is described. There is a list, based on random experience, of materials that have been melted. Change of coil permits some temperature control. Shapes can be cast. There is a comparison with the technique of arc‐melting buttons, and a list of applications. An approximate formula for levitating force is given.
