Bullseye Sheet Glass: 2mm Stiff Black Opal 0101.50

Cold characteristics: 

Consistent colour.

Working notes: 

Stable. No colour shift.

Compared to Black (000100), Stiff Black (000101) has a slightly higher
viscosity, meaning that it is a stiffer glass.

In most kilnforming applications, Black and Stiff Black can

be used interchangeably. Kilnforming applications where

differences between Black & Stiff Black might be noticed

include working with elevated drop ring molds, tack fusing,

and kilncasting.

Stiff Black was originally developed for glass blowing

purposes such as the Roll-up Technique. Using Stiff Black

in kilnformed panels for this application creates a more

uniform viscosity, which is easier to control.

All our glass is COE90, Bullseye Glass compatible and suitable for
applications such as glass fusing, glass casting and glass slumping (unless
otherwise stated in the description).
