These rods are drawn from compatible Bullseye glass.
Working notes
Torch - Remains black except in extremely thin applications when it may become dark grey. It is a soft glass. Beware of heating the glass so much that it bleeds and webs out over other glasses, or use this quality as a design element.
Kiln - Working properties and kilnformed characteristics are consistent with sheet glass.
Cold characteristics
True black.
Each rod is individually labelled. Sold singly.
