We have studied by optical microscopy, small-angle light scattering, and rheology, the behavior under shear flow of a phase-separated lamellar-sponge ternary mixture. We observe in the -rich region the existence of a Newtonian assembly made of closed compact monodisperse lamellar droplets immersed in the sponge phase. Contrary to the classical onion glassy texture obtained upon shearing phases, the droplet size scales herein as , the inverse of the shear rate. This result is in good agreement with Taylor's picture. Above a critical shear rate, , the droplets organize to form a single colloidal crystal whose lattice size varies as .
