Stiff Black 101 is more viscous or dense than Black 100, so use this when differences in viscosity could be an issue. For example, use 101 when firing with a viscous Opaque White 013.

Sheet sizes are:

1/2 Sheet - 20" x 17 1/2"

1/4 Sheet - 10" x 17 1/2"

20" x 20"

10" x 10"

5” x 10”s are perfect for testing colors before you commit to buying a larger piece, or if you just need a small piece. **Please note, 5" x 10" pieces may vary in size.**

Our Samples are larger than Bullseye’s in order to give you a better sense of the color. Keep several on hand to create color palettes and test transparent layers. Strikers will come pre-fired so you can see the fully developed color. Samples available in 3mm Opals, Collage, or 3mm and 2mm Transparents.
