Step 1: Design/Renderings


A sole design is developed in collaboration with the Church/Diocese, Pastor and/or the Art/Building Committees. 


The design of a window may be non-figurative or figurative; may incorporate narratives drawn from the Bible; may represent Saints or Patrons, etc…


DomCat Studios’ stained glass windows quietly reflect the sacred nature of their purpose and the parish in which they reside.  Each church is a unique design expression and special considerations ensure the harmony between glass and building.

Step 2: Layouts & Cartoons


Once the design has been approved, a full size layout and cartoon is drawn for every "light" (opening) of the window.


  • The layout is used as the guidelines for fabricating the window. 

  • The cartoon, a preliminary sketch, is used as the guidelines for the artwork on the glass


The letters & numbers on the layouts/cartoons respresent the glass manufacture and color.

Step 3: Cutting & Painting Glass


Each piece of glass is cut separately and details of flesh, drapery, ornamentation, etc., applied to the glass using pigment (paint).  Then, each piece is placed into a Kiln.  A Kiln is a furnace for firing such things as glass.  Firing takes place at a temperature of 1250 °F., resulting in the pigment (paint) fusing together with the glass to become permanent.


The pieces of glass depicting the faces after they have been traced/outlined.  Once firing in the Kiln, the next process is the matting and "lighting out" phas, which brings the faces to life.  Numerous fires in the Kiln throughout the process. 

The Process: Creating Religious, Stained Glass Windows for Churches



Stained glass, as an art and a craft, requires the artistic skill to conceive an appropriate and workable design, and the engineering skills to assemble the piece.  Stained glass windows are created by cutting pieces of colored glass to match a drawn template and setting them into place in a mesh of lead cames. Large stained glass windows are made up of multiple stained glass panels or “light” openings.  Details such as facial features can be painted on the surface of the glass.  Stained glass is extremely durable and many windows have been in place for centuries.

Step 4: Glazing


Once the window is cut and painted, the pieces are assembled by slotting them into H-sectional lead cames and soldered together at the joints.

Step 5: Waterproofing/ "Putty"


After each panel is assembled, they are waterproofed/sealed.  A term we refer to as "Putty".  Putty is an oily cement used to seal and harden the windows between the glass and lead. 

Step 6: Installation


Finally, the finished stained glass windows are installed into the frames of the  Church building. 


The panels are set into the window's frame using mullions & screws, which individually support each stained glass panel.
