Fast, Slow & Delayed fuse
Posted 03 August 2019 - 10:03 PM
I've made my fuse with 6 ply cotton string.
My KNO3 is soft & milky white & I worm it a bit to get rid of moisture within.
My AF C is from Indian species of Ziziphus tree which is shrub kind of plant
Sulphur as usual.
In 75/15/10/5(dex) I screen them 5-6 times grind them with mortar & pestle and again screen 2-3 times. Then wet with water.
This way I'm getting fuse equivalent to visco.
Now I intend to prepare fast As well as delayed fuse too.
Seniors please help me on this.
I do have Acetone, doctors spirit & methylated spirit in my stock also. Mentioning if those are handy on this project.
I understand seniors here don't care about 'Thanks in advance', they just do help.

"fast" visco fuses are typically made by wrapping granulated composition in spiral threads, taking advantage of the air pockets and surface area of the granules to increase the burn speed.

My intention was to know the process(if there is any) of making a fuse faster than a fuse made by dipping in 75/15/10/5(dex).
Sometimes back I saw a video of three fuses(not in 'quickmatch' form) burn rate comparison. First one was a delayed fuse. Second one was a normal black match & the third one burnt mutch faster.
