He worked primarily in oils (glazing)  but also graphics - conté, charcoal, pencil, inks - silk screening , gouache, egg tempera etc.; developed his techniques, mediums, finishes; a few small sculptures in copper or papier mâché including his whimsical 'Wampus Burds' (see a later version below under 'The Eighties'.) Burrell instructed in many centres, both groups and individuals; set up the first art school in Nanaimo (1961/62) in the former Beban House; had numerous successful shows of his own work, including juried shows. He had acquired recognition and thus material assets by mid 1960s. However teaching required a different frame of reference - time-consuming preparations to suit each class and location, driving long distances in all weathers, often providing materials for students who forgot or misunderstand necessities. After six years he concluded he must withdraw these services and set out on his solo path. In 1966 his sold-out show of his works at Pandora's Box gallery in Victoria convinced him. Many students, although sorry to lose him, not only understood but certain of them organized successful solo shows for him in their respective towns.
