When he was 13, Paul was exposed to the Art Nouveau movement through the work of Louis Comfort Tiffany, a popular designer known for his stained glass works in the era. Katrich attended Wayne State University and received a degree in art history - which introduced him to the tens of thousands of years of ceramic history.
After college, Katrich worked as a professional restoration artisan, which involved (among other mediums) his formal acquaintance with historical ceramic techniques and craftsmanship. Patrick describes this experience, more than any other, as the spark that pushed him from art pottery expert to creator.
Katrich is a genius with glazes and developed a plethora of modern glazes that accurately reflect the look of pottery from the Arts and Crafts movement of the early 1900s. Katrich throws his pottery individually, and there is no commercial production in his process. Paul creates lusterware - pottery that is distinct from the more matte-looking Grueby works of their time. He employs bright colors, abstract designs, and sticks largely to vases as his major form. Paul is often compared to George Ohr, a famous abstract artist and potter from the early 1900s. However, Katrich rejects this claim, espousing Ohr as “supernatural”, and describes his work as simply a “link” to Ohr and the early art pottery movement.
