Black Granite Ripple Irid (100-RI71) 3mm

Black is the least viscous of all glass colors, therefore it will flow faster than other colors. Take note of this when firing with the glasses in the white family, as these are the most viscous colors.

Sheet sizes are:

1/2 Sheet - 20" x 17 ½"

1/4 Sheet - 10" x 17"

10" x 10"

5" 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.
