Item Name: Boro Batch - Small Batch - Dark Transparent Cobalt - Middle Batch SKU: BB-SB-134-OPTION134 Description: BB SB Dark Transparent Cobalt is a dark cobalt blue transparent borosilicate color rod designed for torchworking. It is pulled as solid rod and formulated to stay highly workable in the flame while producing a deep, saturated blue. This color is intentionally very dark for a transparent, making it a strong choice when you want rich color density without switching to an opaque. How it is used: In lampworking, this rod is worked in a neutral to slightly oxidizing flame and is commonly used for blown sections, encasement work, and layered color where you want depth and a clean transparent finish. It is especially effective for overlays on clear, for building transparent color backs, for pulling stringer that reads dark and crisp, and for adding bold transparent accents to sculptural details. Because it is a darker cobalt, it is useful when you need strong color presence in thinner applications compared to lighter transparent blues. How It's Sold: This item is available by the pound (LB) or 1/4 lb.
