How to Use Piping Gel to Make Church Stained Glass Windows
Use liquid leading to create inexpensive, beautiful church stained glass windows. (stained glass image by Andrew Breeden from

Traditional stained glass windows for churches can not only be costly, they can take months or even years to finish. There's an alternative to the traditional method of cutting and grinding the glass than laying it in between leading; you can create a beautiful window with the look of a stained-glass leading by using liquid lead piping gel, or liquid leading. Not only will you complete your project more quickly, but you'll save money too.

Skill level:


  1. 1

    Clean the glass using the vinegar/water solution. Allow the glass to dry for at least one hour.

  2. 2

    Place the pattern on a flat surface, and then position the glass on top of the pattern. Make sure the pattern is positioned exactly where you want to place the liquid leading, and secure the pattern to the glass using masking tape.

  3. 3

    Open the applicator bottle of liquid leading using a sharp knife on the applicator tip. Tap the tip of the bottle on a hard surface to dislodge any air bubbles. Hold the bottle down, squeeze firmly, and follow the lines of your pattern as you evenly apply the liquid leading on top of the glass.

Tips and warnings

  • Since temperature and humidity may affect the liquid leading, you should apply the leading when the temperature ranges between 55 and 80 degrees Fahrenheit and the humidity range is between 20 and 60 per cent.
  • Keep containers tightly sealed when not in use.
  • The width of your leading bead is based on the amount of tip you remove from the applicator tip. For example, if you want a fine line, cut about 1/16 inch down from the tip.
  • If you make a mistake as you are applying the liquid leading, let the liquid leading dry and then lift it off with a craft knife. Clean the glass and begin again.
