Jessica Potenza, Montreal artist, paintings available at Chase art Gallery. Jessica Potenza is a self-taught artist. Jessica’s painting technique involves combining acrylic and ink with pigments, papers and materials she collect throughout her every day life. Her tendency to use natural pigments such as coffee began early in her artistic explorations, when the only paint substitutes at her disposal were those found within arms reach while at home or on the road working with horses. These pigments, usually selected to signify either her intentions with each piece or her whereabouts, make the work more personal, more meaningful if you will.
