"Time fuse" usually refers to tightly-wound fuse that's specifically made to burn at precise, accurate and reliable intervals of time. Our "Premium Time Fuse, 1/4-inch" is a tightly-wound fuse that's specifically made to burn at precise, accurate and reliable intervals of time. It's mainly used as the timing component in aerial shells; the initial "lift charge" ignites the time fuse, which gives the shell time to reach its desired height before exploding in the air.
For the amateur hobbyist, time fuse is a vital component when making your own fireworks, especially when it comes to aerial shells and other "airborne" pyrotechnics. It offers several important advantages compared to traditional Visco or safety fuse. Time fuse is manufactured to provide a much higher degree of timing accuracy, most notably when it's cut into small sections of 1 inch or more. Its relatively thick diameter also makes time fuse easier to cut into clean sections for reliable timing.
Our "Premium" version is the highest-quality time fuse we offer, and most likely it's the best you'll find anywhere else, for that matter. Actual diameter measures .236 inches (or 6mm) and burns at 2 seconds per inch. Each roll is 10 feet in length.
