Approximate analytical solutions describing the skyrmions given by rational-map ansatz are obtained. At large baryon numbers, these solutions are similar to the domain wall or to spherical bubbles with energy and baryon number density concentrated at their boundary. A rigorous upper bound is obtained for the masses of rational map multiskyrmions, which is close to known masses, especially at large B . The main properties of bubbles of matter are obtained for an arbitrary number of flavors.
