With a 4lb test strength and ultra-thin 0.12mm diameter, this 125-yard crystal-colored spool offers exceptional durability and tangle resistance, ideal for jewelry making and bead weaving. Designed for professional finish using a thread burner, it’s a trusted choice by creatives seeking strength and precision. ## Description When you want to create necklaces or bracelets quickly and efficiently, Fireline is up to the task. This is a microfused, braided bead thread consisting of Dyneema, a gel-spun polyethylene which is known as the strongest fiber, per diameter, ever created. It has an unbelievably high tensile strength and has been recommended in numerous how-to articles on beadworking. Originally used in the fishing industry as a strong fishing line, the thread was adopted by the jewelry making community and has been super popular ever since. Fireline comes in 5 sizes: 2lb. test strength with a .003”/.07mm diameter, 4lb. test with a .005”/.12mm diameter, 6lb. test with a .006”/.15mm diameter, 8lb. test with a .007”/.17mm diameter, 10lb. test with a .008”/.20mm diameters and 14lb. test with a .009”/.22mm diameter. The spools come in a variety of lengths and in 3 colors: clear, black and smoke grey. For stringing and weaving we suggest English beading needles. Use a #12 for 2-6lb. test and a #10 for larger diameters. To finish off your Fireline jewelry your best option is a thread burner. The Beadsmith Thread Zappers are a perfect solution. You can control exactly where the heat is applied. Tie a knot to finish your project and burn the end. A small ball will form on the melted end, preventing the knot from untying. ## Features - FIRELINE: This is a microfused, braided bead thread consisting of Dyneema, a gel-spun polyethylene which is known as the strongest fiber, per diameter, ever created. It has an unbelievably high tensile strength and has been recommended in numerous how-to articles on beadworking. - DETAILS: Made in the USA, our Fireline is 4lb. test and comes in a crystal color. The cord measures .005” (.12mm) in diameter. The 125 yards are wound on a spool that is secured with a clear plastic clip. Keep your thread secure and organized. - EASY FINISH: Because this is a super strong material, we recommend using sharp, precise scissors for cutting the string. However, the thread can also be burned instead of snipping. A thread burner is easier to use and more precise. This method seals the ends, which prevents frayed edges or split ends. - VERSATILE: Originally used by fisherman as a high-quality fishing line, this thread took off in the jewelry making world. It can be threaded on a needle and used for stringing or bead weaving. The thread does not stretch, or tangle and the strength of the cord is essential when working with heavier beads and findings. - THE BEADSMITH- 40 years in the making! 💎 Trusted to bring you the best quality beads, tools, and supplies.
