This sheet carries eight wireframe sphere illustrations drawn in precise black line, each mapped with a different grid of latitude and longitude lines that describe a three-dimensional form. The eight vary in angle and proportion: upright globes seen face-on, a wider flattened form, a distinct equatorial ring form, and one open torus that reads as a ring rather than a solid sphere. Printed on clear film, the black line work reads cleanly over any glass color placed beneath it.
These are water-slide decals for pre-fired glass. Soak until the film releases from the backing, slide it onto a clean, dry pre-fired surface, and smooth from the center outward to remove water and air. Allow the piece to dry completely before firing. Because the decal bonds on top of the glass rather than fusing as a structural layer, it works with any COE glass.
Can I apply these to a piece I have already fused?
Do the decals need to match my glass COE?
How do I prevent trapped bubbles?
Specifications
SKU: 155452 Sheet size: 4 x 5.25 inches Design: 8 wireframe sphere and globe illustrations, black line on clear film Format: single printed water-slide decal sheet Compatible with any COE glass Working Notes
Clean the glass surface thoroughly before applying. Oils, kiln wash residue, or fine dust beneath the film can cause lifting or uneven adhesion. If placing only one or two designs, cut them apart before soaking for easier positioning. Let the applied decal dry completely before firing, since rushing can cause steam-related defects. Every kiln fires differently, so test a small piece and anneal for the thickness of your glass.
Suggested Firing Schedule (a starting point only, not a guarantee of results; every kiln fires differently, so test a small piece first and anneal for the thickness of your glass): Ventilate the kiln well up to 1000 degrees and fire slowly below 500 degrees. Ramp 50 degrees per hour to 185 degrees, hold 20 minutes. Ramp 150 degrees per hour to 300 degrees, hold 15 minutes. Ramp 250 degrees per hour to 500 degrees, hold 15 minutes. Ramp 600 degrees per hour to 1000 degrees, hold 10 minutes. Then ramp to a final 1240 to 1370 degrees, held about 10 minutes, staying toward the lower end to preserve density. Anneal for the thickness of your glass.
