An equation is derived for the kinetics of dissolution or growth of uniform solid grains uniformly dispersed in a liquid. The conditions under which sand dissolves during glass melting are discussed and a simple formula for the pertinent mass transfer coefficient is suggested. Some factors governing the lifetime of silica grains are analyzed.
