These rods are drawn from compatible Bullseye glass.
Working notes
Torch - Develops a range of streaky pinks in the flame. Work in a cooler, oxidizing atmosphere. May develop a light brown colour on the surface of the glass if worked in the presence of too much propane (or fuel).
Kiln - Rod-only glass style. A linear, streaked design may develop upon firing and may be visible whether fired lengthwise or on end. Slight variation in colour with different production runs.
Sapphirine is designed to appear light blue in transmission and slightly brown in reflection in its cold state. It is designed to be streaky pink in transmission with slightly brown undertones in reflection after it has been flameworked.
Each rod is individually labelled. Sold singly.
