We used fine frit for the thin line of black between each layer of medium colored frit to add texture. Try using different colors of glass blanks to change the look of your project. We chose to drape our project with the marbling design on the outside, but you can also drape it with the design on the inside. Always use the least amount of glue possible. Excessive use of glue can cause carbonization and bubbling. To cover large areas with frit, use a plastic spoon. For smaller areas, use a straw scoop for more accurate placing of frit. Make a straw scoop by cutting a plastic straw in half at an angle. The angle creates a point for precision placing of frit.
1. Gather all materials. Lay glass blank on work surface.
2. Find center of glass blank and apply glue in the center about the size of a quarter. Use a Cotton Swab to spread glue in circle.
3. Apply first medium frit color over circle of glue using plastic spoon.
4. Make a thin ring of glue around the circle. Apply fine black frit to ring with a straw scoop.
5. Make a thicker glue ring around the outside of the black ring. Apply second color of medium frit. Repeat Steps 4 and 5 to create concentric circles that alternate between a thick colored frit ring and a thin black frit ring frit. Build concentric frit circles all the way out to the edge of glass blank.
6. Once glass blank is fully covered in a layer of concentric frit circle, drag toothpick through the rings pulling from the center out to create marbling effect.
7. Spray with hairspray to hold frit in place.
8. Spray with hairspray to hold frit in place.
9. Full Fuse project according to firing program in the Warm Glass Training Guide.
10. Center fused project over a large floral form that is coated with three dry coats of Boron Nitride Spray. Slump according to firing program in Warm Glass Training Guide.
