The buoyant rise speeds of single bubbles of varying composition and size in a soda‐lime silicate glass melt were measured. The measured rise velocities were compared with the steady‐state velocities predicted by the Stokes and Hadamard‐Rybczynski formulas. In all cases the data fit the latter expression for steady‐state rise speed far better than the Stokes formula.
