Why a Stained Glass Window Takes 18 Months: Inside Cavallini & Co.'s Sacred Art Studio

In an era of instant gratification, Cavallini & Co. is a deliberate exception. The Texas-based stained glass studio, profiled in Episode 2 of The Cavallini Legacy on The Building Texas Show, designs and installs handcrafted sacred art for churches across Texas and beyond. As host Justin McKenzie notes, the process is anything but quick: 'Employees coming in here working on a project that might take a year and a half to complete because it is detail-oriented... It's not AI is going to create it in 30 seconds.'

The episode takes listeners inside the studio to reveal the hidden complexities behind every window. Thematic development alone requires deep collaboration with parishioners, often tracing narratives from the Old Testament to the New Testament—from Creation and Moses to the Nativity, Resurrection, and Ascension. But the artistry goes beyond imagery. Each panel contains hidden structural engineering, including rebars that transfer weight to the frame, preventing the glass and lead from bowing under their own weight.

A centerpiece of the conversation is the story of windows salvaged from St. Mary's Catholic Church in Port Arthur after Hurricane Rita. Cavallini purchased the Mysteries of the Rosary windows from the Diocese of Beaumont 18 years ago, storing them until they found a new home at Our Lady of the Holy Rosary in Houston. The original church had been destroyed by a natural gas explosion that claimed a parishioner's life. Adrian Cavallini sent photographs of the stored windows to a committee member who, in the elder Cavallini's words, 'just fell in love with them.' Now, the studio is creating the Luminous Mysteries to complete the set, bridging two generations of Texas congregations.

McKenzie reflects on the broader lesson: 'I worry for our economy and our workforce on how do we bring that patience back to something as meaningful as the work you're doing.' The episode makes the case that patience and craft are inseparable from sacred art, and that no AI template can replicate the result.
