We report an aging soft colloidal suspension that can be tuned continuously and reversibly between the glass at low temperature T and the liquid state at high temperatures. The glassiness is characterized by a noise temperature x ranging from 0.5 to above 3.0. The glass transition temperature has been obtained as a function of the weight concentration of microgel particles. We also probe the evolution of the structural relaxation time τs(t) of this system in the glass state, using both particle tracking micro-rheology and linear oscillatory measurements in combination with the soft glassy rheology model. Both methods consistently yield a linear increase of τs(t) with age.
