William Popiel started in stained glass at a beginner’s class in Saskatoon in 1981. His glass art is created from hand sketches and drawings prepared using a workflow that starts with pencil, charcoal and paper and evolves into computer graphics and cartoons. Popiel's glass art can have elements worked by glass blowing, fusing, sandblasting, lead sculpting, lead overlay, silk screening, and glass painting methods.
Presently, he has been focusing on designs incorporating subject content from various paths of spirituality and colour energy theory. He is exploring various aspects of the well-known Christian icon of the fish both in painting with stained glass colours and fused in glass. Popiel is also producing a series of work entitled “Symbols”. This explores script symbols of purpose, power and intent used by oracles, sages and others through the ages.
