Joplin is about to get another new mural on Main Street. The “Rise of the Phoenix,” a triptych, or three-panel ceramic mural, is being installed this weekend on the south end of the building that houses Phoenix Fired Art at 1603 S. Main St. A small tent and some chairs will be set up for people who want to watch the process, said Heather Grills, the art studio’s owner and executive director.
