Yes, I've tried this in conjunction with waxed cotton balls with magnesium chips. I was hoping to find a higher temperature ignition source to more quickly ignite the magnesium on the BOFs (balls o' fire). I tried it with 2" of fuse but it burned too fast and if the cotton ball was not totally torn apart, it and the magnesium did not light; not enought oxygen. It makes me wonder if the fuse robs oxygen while it burns (?). I'll keep experimenting but will probably go with 4" sections and use them as a suppliment to the BOFs.
