Description
 

Unique! BlackJack goes almost clear when hot, but self-strikes back through brown to near-black depending on how thick you use it. BlackJack likes an oxidizing flame, but does not reduce with gray streaks like most black boro colors. In the curls shown here, we had to get the glass right on top of the light to see the brown where it's thinner. BlackJack is not suitable for thin stringer work where you want the stringers to look like a dense black, but it's the perfect color for very specific things, like sculpting without the graying. Because this glass goes clear when hot then self-strikes, it is useful in applications where, say, you want to mask a weld.

Tube Ordering Policy
  • Sold by diameter.

    Tubing is
    charged by its exact weight, and you will only pay for what you receive. When we are picking orders we get as close to the requested weight as possible without going over. For example, If you order one pound, we will pick tubing that is 3/4 - 1 lb. and you will be charged by the hundredth of a pound for that glass.

    If you have a specific weight that you need, please request it in the comments section of your order. In these cases it is helpful if you order above your requested amount (i.e. if you need exactly 1.5 lb., order 2 lb., and in the comments section of your order write in a request for 1.5 lb. When we receive your order we will send as close to 1.5 lb. as we can get, and you will only be charged for what you receive.)
