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 viscous Opaque White 013.

Sheet sizes are:

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

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

10" x 10"

5” x 10”

Sample: 2 1/2” x 3”

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.
